Thats the sweet spot. Pitching Trajectories.- 5. endstream /R [52 73 308 791 ] Adding to that is the fact that bats have narrower handles than in the past which makes the bat less sturdy and more prone to breakage. Both the swinging bat and the pitched ball possess kinetic energy, which is generated by the players who swing the bat and throw the ball. The pain of hitting away from the sweet spot motivates you to learn how to find itthat, or buy a composite bat with a vibration damper in the handle. However. /V 21 0 R R. Cross, Physics of Baseball & Softball, DOI 10.1007/978-1-4419-8113-4 14, c Springer Science+Business . >> << not apply to baseball or softball bats. 9-d\DA=cZ0Q>gIM$$;cd2O@&a;X,Nn_aP(]I1aRc(K1^ue> endobj The hitch is, no one knows for sure how close the optimal spot for hitting is to the sweet spot that players know and love. 13 0 obj /ColorSpace [/Indexed /DeviceRGB 255 28 0 R] Basic Physics.- 2. Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. << /P 20 0 R Largest thickness - The sweet spot Bat - Ball Collision Diagrams Vball 1 = Vb Vbat 1 = V2b V bat 2 = V2a Vball = V1a Before After Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. To increase the acceleration of the ball while it is still moving, a bat that strikes it harder will most likely accelerate faster. At other impact points, the impact is usually felt as a sting or jarring of the hands and forearm, particularly if the impact occurs at a point well removed from the sweet spot. 1 inch in length is huge. Jessy is an avid baseball fan and writer for the popular website, Baseball Writes. 5P8$ BaPR+"dUkbQ]YH`P. /N 21 0 R 232 g bat 871 g bat 1333 g bat. In order to determine how each of the sweet spots influences the "feel" of the bat, measurements were made of the impact forces transmitted to the hands. Also shown for comparison is a bounce off a heavy block of granite so that the COR of the ball can be determined. The length and weight of a bat is tailored to the size, strength and hitting style of the individual player. endobj Boxing. The above results are more or less as expected, in that light bats can be swung faster than heavy bats. The mass moment of inertia (MOI) is a measure of the distribution of mass in the bat. The shoulders reach maximum speed first, then the upper arms, then the forearm and finally the bat. Edd Roush holds the distinction of being the heaviest Major League Baseball player in terms of weight. The following three movies show a batter swinging three different bats as fast as possible, filmed at 25 frames/sec. Ash bats, on the other hand, are more flexible, making them perfect for contact hitters. << 2. The fundamental mode of a wood bat has a node located typically about 17 cm from each end and a frequency typically of about 170 Hz. If you hit a baseball anywhere but at the bats so-called sweet spot, you feel all those vibrations in your hands, and about 10 swings laters youll have a bruise. /Gamma [1.8 1.8 1.8] The second definition is where the ball comes off the bat fastest. George has always been passionate about physics and its ability to explain the fundamental workings of the universe. Why? >> Colloquially, a player who hits the ball solidly is said to have gotten the sweet spot of the bat on the ball. Are you a fan of composite or wood? However, the COP shifts a long way toward the handle when a batter holds the handle, and plays only a minor role in the feel of the bat for an impact at the sweet spot. As a result, the bounce is relatively weak at the tip and near the center of mass. the location where coefficient of restitution is maximum. Opines that close to where the point of percussion occurs is the "sweet spot." Explains that a net force hit on small mass will go farther than large mass. So. The sweet spot (where you want to hit the ball consistently) is located about 2 in from the end of the barrel to about 6-7 in on an adult bat. So, well hit balls are struck at the sweet spot. One of the definitions of the "sweet spot" is the location of the node at the barrel end of the bat. A high performance bat has a strong trampoline effect and hence a relatively large COR. Good eyesight. It does not store any personal data. As a result, the fundamental and second vibration modes are both excited with about the same amplitude. /V 19 0 R Image by Pulkit Sinha Own work. >> Its center of mass is 52.6 cm from the knob end. Movies showing the collision of a baseball with a cricket ball and the collision of two billiard balls are shown in the page on collisions. The bat then magnifies that force by a factor of about 100-5,000 lb or so when it collides with the ball, enough to squash the ball in half. How much force does a baseball bat generate? Where is the sweet spot on a bat? This is why it is important that baseball bats are made out of a hard material that can maximize the energy transfer while also reducing the risk of injury to the player. Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. It is not difficult to swing a bat. For a fastball, this wake gets pushed down, which then pushes the ball up .. /P 23 0 R stream 16 0 obj Both papers can be downloaded. Bamboo bats are the lightest of the three woods, making them great for players who need to swing fast. The heavier the bat, the higher the bats bat speed. When it comes to bats, one inch in length is equivalent to an ounce of weight. Curve Balls Sweet Spot / Corked Bats / Questec-MLB Zone Evaluation. I havent listened to different recordings of hits to see if theres a noticeable difference, says Russell. If you drop the weight, you will be able to use the bat with greater control and power. White ash, sugar maple, true hickory, yellow birch, red oak, and Japanese ash are the six wood types that can be used in bats in Major League Baseball. Otherwise, the effective mass of the bat is less than its whole mass. The first is where the bat feels best in your hands when you hit. >> Baseball Sweet Spot Science ScienceC 19.8K subscribers 19K views 6 years ago It turns out there's a lot of physics that goes into the sweet spot on a baseball bat! window.mc4wp = window.mc4wp || { >> Baseball bats are an integral part of the game of baseball, and their physics is an important aspect of the sport. /Filter [/ASCII85Decode /LZWDecode ] Is it possible to hit heavier bats harder? I simply wanted to know whether a hand launched ball spins at around 100 rpm or whether it could be as high as 1000 rpm. The Sweet Science. 21 0 obj Then can't we add to the list of deeper queries some of . /N 25 0 R When a wake is pushed down, a fastball is pushed up. The cookie is set by the GDPR Cookie Consent plugin and is used to store whether or not user has consented to the use of cookies. Interesting information on the behaviour of a ball can be obtained by bouncing it on a force plate or on a piezo to measure force vs time. Taking the rotation rate as 3/8 revolution / 0.04 sec gives 9.4 revolutions / sec or 560 rpm. We also offer a variety of resources for baseball players, including tips on hitting, pitching, and fielding. This force is required to change a 5 1/8th-ounce ball from a speed of 90 mph to a speed of 110 mph, this distorts the baseball to half its original diameter and the bat is compressed one fiftieth of its size.. Only a small fraction of that huge force gets back to the handle to trouble the batter. Specifically, what forces and torques are exerted on the handle, and in what directions do they act? /N 16 0 R For small swings of a pendulum, the incoming and outgoing speed of the pendulum bob is proportional to its horizontal displacement, so the relevant ball speed ratios can be measured directly off the film with a ruler. produce and innovate modern day cricket bats. Rather, most coaches and others think in terms of wrist torque, which is probably much too small to provide the necessary large couple near the end of the swing The couple must come mainly from the two arms, not the wrists. /N 22 0 R It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. 4) Good quality bat grip Investing in a good quality bat grip will help improve your grip and increase your odds of hitting the ball in the sweet spot which can reduce the chances of breakage. The bat and the forearms are locked at right angles at the beginning of the swing, by locking the wrists, otherwise the bat would start to rotate in the wrong direction at the beginning of the swing. /N 18 0 R The ratio of ball speeds after and before colliding with the bat is called the is combined with the kinematic properties of the bat (determined from the moment-of-inertia of the bat and the impact location) to obtain the Bat-Ball Coefficient-of-Restitution, or BBCOR for the collosion. The film is shown here, taken at 25 frames/sec. Generally, heavier bats are used for power hitters, as they are able to generate more force when swinging. Hence, there are two vibration nodes in the barrel. /R [316 73 572 791 ] To view the purposes they believe they have legitimate interest for, or to object to this data processing use the vendor list link below. When a bat is made out of a hard material, it allows the bat to transfer more energy to the ball when it is hit, enabling the ball to move faster and farther. In file A, the tangential COR was surprisingly high, about 0.3. This minimises discomfort to the hands caused by vibrations excited by the impact. In this article, well explore the various components that go into making a baseball bat, as well as how they work together to help a hitter put their best foot forward. All of these are needed to hit a baseball at the Major League level. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. If you hit the ball on the bats node, the vibrations from the impact will cancel out, and you wont feel any stinging or shaking in your hand. Sign up to receive Popular Science's emails and get the highlights. Most people find that an impact between the nodes of the first two modes (node1 and node2 in the diagram) feels best since both modes are then excited only weakly. Manage Settings If the vibration frequency is less than about 1000 Hz, the end result is that ball comes off the bat at a lower speed than off a wood bat of the same weight and swing weight. { << The same batter swung the 871 g bat at 33 radians/sec on average, and he swung the 1333 g bat at 26 radians/sec on average. The batter might find that he needs to change the way he swings the bat if the swing weight is altered, or he might have a grooved swing technique and swing every bat the same way. Regardless of age, the weight of the right handers bat is crucial. The 232 g bat was swung at 45 radians/sec on average (by the batter in the film). Although the Hickory bat wood is the most difficult to swing, it is also the most powerful, making it the hardest of all bat wood species. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. A paper on this subject can be downloaded here. As the ball leaves the bat, the potential energy is converted into kinetic energy. Elastic behaviour in the vertical direction is described by a number called the coefficient of restitution (COR) which is about 0.5 for a baseball, depending on ball speed. Licensed under CC BY-SA 2.0, via Flickr Creative Commons. Metal bats, on the other hand, are lighter and more forgiving, but they lack the power of iron bats. A ball that would travel 400 feet in "normal" conditions goes: 6 feet farther if the altitude is 1,000 feet higher 4 feet farther if the air is 10 degrees warmer 4 feet farther if the ball is 10 degrees warmer 4 feet farther if the barometer drops 1 inch of mercury 3 1/2 feet farther if the pitcher is . The ball bounces backward spinning counter-clockwise. The cookie is used to store the user consent for the cookies in the category "Other. Aluminum tubes are 24 to 35 inches (61 to 89 centimeters) long and 2 to 3 inches (5 to 7.6 centimeters) in diameter for making an aluminum bat. } The horizontal speed at the contact point depends on the rate at which the ball spins, as well as on the horizontal speed of the centre of mass of the ball. The flight of a ball through the air depends strongly on how fast it spins, and in what direction it spins. For that reason, the walls of a hollow bat need to be relatively stiff so they can vibrate at a frequency larger than 1000 Hz. The collision of a bat and a ball can be understood by treating the bat as a heavy ball whose mass depends on the impact point. << The average hitter needs about 50 milliseconds to instinctively assess the speed and location of an incoming pitch. All batters knew was that when you made contact about two-thirds of the way down the bat, it felt good in your hands. Sara Chodosh Where is the center of mass in a baseball bat? This equation for acceleration can , Dry ice is the name for carbon dioxide in its solid state. At some point you will feel almost no vibration when you tap. A bat is essentially a long stick. /P 8 0 R } If there was no loss of energy during the bounce then COR would be 1.0. A great way to keep a rhythm throughout your swing is to step or stride toward the pitcher. If the ball is struck at the sweet spot of the bat, then . /V 18 0 R What happens to the dry ice at room pressure and temperature? << The results are very surprising. event : evt, The mode shape of a baseball or softball bat is a simple flexing bending shape that has parts that move and parts that don't. Every bat has a point about seven inches in from the tip of the bat that doesn't move, that doesn't vibrate, called a node. endobj I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. When a player has a bad hit and fails to hit the sweet spot, it causes vibrations which can cause the bat to bend or break. There is enough physics in it to keep a PhD student busy for a few years, but it could also be done by any high school student as a simple introduction to the physics of baseball. . Learn how to add this technique to your swing while still keeping a balanced, relaxed approach to the ball. A similar result is obtained when swinging cylindrical rods, as described in a paper that can be downloaded here. The sweet spot of a bat exists because bat vibrations are not excited significantly at that spot. Sniper Skin carries a line of great bat grips which are easy to install and remove while virtually eliminating the sticky gunk left on your bat. Continue with Recommended Cookies, Copyright 2009-2023 real-world-physics-problems.com. The popularity of maple bats has increased dramatically since the introduction of the first major league-sanctioned model in 1997 due to their hardness, durability, and performance. A hollow aluminum bat sounds a lot different to a solid bat since the wall of a hollow bat can vibrate in and out like a drum. The direction of the centripetal force is toward the center of the circle followed by the path of the CM. /R [52 73 308 791 ] Coefficient of Restitution = Relative speed of bat and ball after collision/ relative speed before collision, where "speed of bat" is the speed of the bat at the impact point. Baseball is a beloved American pastime, with millions of people playing the game recreationally or professionally each year. Ball Trajectories.- 4. Hit the ball at this spot, and the least amount of vibration will travel throughout the bat. Softer and less dense varieties of maple that are more likely to break have been banned by Major League Baseball. This includes both the length of the barreltop part of the batand its diameter The longer the barrel, generally, the larger the sweet spot for hitting the ball The standard diameter is 2 , and big barrel bats, allowed in some leagues, are 2 5/8. We can then ask a similar question. In practice, batters tend to prefer bats that are lighter, rather than more powerful, since lighter bats are easier to swing and make it easier for the batter to connect with the ball. Adair provides a few answers in his book The Physics of Baseball but he does not give the directions or the torques. endobj A heavier bat is a better choice for hitting faster balls. << Also,. 2) Choose the right turn model As discussed earlier, a wider handle will improve bat durability and reduce the likelihood of breakage. The higher the number, the heavier the bat will be, meaning it will have more mass and therefore more power when it makes contact with the ball. Out of these, the cookies that are categorized as necessary are stored on your browser as they are essential for the working of basic functionalities of the website. The second definition is where the ball comes off the bat fastest. He received his Ph.D. in physics from the University of California, Berkeley, where he conducted research on particle physics and cosmology.

When a player has a bad hit and fails to hit the "sweet spot", it causes vibrations which can cause the bat to bend or break. Uncovering The Mystery Behind The Golden Glove Award What It Takes To Receive This Prestigious Honor, How To Restring A Rawlings Baseball Glove Web: A Step-by-Step Guide, Exploring The Meaning Behind The Phrase Peanut Butter Jelly With A Baseball Bat. /Matrix [0.4497 0.2446 0.02518 0.3163 0.672 0.1412 0.1845 0.08334 0.9227] >> According to Newtons third law, every action has an equal and opposite reaction. /V 5 0 R The COR for a collision between the bat and the ball is less than 0.59 when energy is lost to vibrations, but can be greater than 0.59 if the bat has a trampoline effect on the ball. But the bat vibrates strongly for impacts near the tip of the bat and near its center of mass. The following material has been expanded considerably into a 324 page book Physics of baseball and softball published by Springer in March 2011. /R [52 74 308 585 ] /N 19 0 R Most contact and power hitters use maple bats because the material is the strongest and has very little give, which is why they swing ash bats. If you hit the ball on the "sweet spot" of the bat, you get the feeling of a solid connection with the ball. In general, swing weight increases with actual weight, but swing weight also depends on bat length and weight distribution. For most bats all of these "sweetspots" are at different locations on the bat, so one is often forced to define the sweetspot as a region, approximately 5-7 inches from the end of the barrel, where the batted-ball speed is the highest and the sensation in the hands if minimized. George Jackson is the founder and lead contributor of Physics Network, a popular blog dedicated to exploring the fascinating world of physics. Lighter bats, on the other hand, are better suited for contact hitters who are looking to make contact with the ball and generate less power. Baseball bats have a sweet spot which is the ideal location on the bat to hit the ball for maximum performance. When he's not busy exploring the mysteries of the universe, George enjoys hiking and spending time with his family. According to Newtons second law of motion, the acceleration of an object equals the net force acting on it divided by its mass, or a = F m . Neither the CoP nor the 'sweet spot' maximises the velocity which the ball gains from the impact. As discussed earlier, missing the sweet spot can cause vibrations in the bat. A superball has a COR of about 0.9, a baseball has a COR of about 0.5 and a sorbothane ball has a COR of about 0.1 (ie it hardly bounces at all). A rough estimate would be that the ball rotates 1/4 revolution while it is in the pitchers hand. It is not easy to find information on the actual rate of spin of a softball in flight, but it is relatively easy to measure, at least at low ball speeds and low spin speeds. Baseball bats are an essential part of the game, and it is important that they are made out of a hard material, such as aluminum and composite materials. The bat was swung through an axis 143 mm from the knob end. I have done quite a bit of independent research in both areas. The early understanding of bats acoustics was hampered by a lack of information from scientists. If the bat approaches a ball incident at speed v. Are heavy bats are more powerful than light bats? Except, of course, when you hit the sweet spot. So, why does the MLB still use wooden bats? 5 0 obj The lines behind the bat, passing through the axis, mark out angles of 5, 10, 15, 20, 25 and 30 degrees. The true CoP should be measured from that point. There is enough physics in it to keep a PhD student busy for a few years. (The first person to really investigate sweet spots did so on tennis rackets.) One question that can be answered this way is "Where on the bat does the ball bounce best?" /R [52 73 308 791 ] See, the trouble with wood is that it vibrates. The tubes were suspended by a length of string so that they could vibrate for a long time without damping. The ideal is the 110 turn model. We also use third-party cookies that help us analyze and understand how you use this website. And though the term is almost always used exclusively to talk about baseball, the scientific principles that explain the sweet spot are actually true of tennis rackets, hockey sticks, and cricket bats as well. Hitting a baseball in the sweet spot on a baseball bat gives the best rebound and does not twist the handle of the bat in the hitter's hand. Metal bats have the distinct composition of wood bats and the balance of pop and density that wood bats lack, whereas wood bats fly faster and farther when hit by wood bats. 12 0 obj The first is where the bat feels best in your hands when you hit. The second you swing one, there is a certain romance to it. This cookie is set by GDPR Cookie Consent plugin. Youre already losing about half the balls energy to deforming it (baseballs squish down to half their diameter as they impact a bat). /BitsPerComponent 8 It is almost as easy as walking. It is critical for any baseball player to know his or her bat weight before purchasing one; you must consider the weight of the bat in order to purchase it. How do you know if a bat is too heavy for a boy? The swing weight of the bat (that is, its moment of inertia) can be determined from the measured period of oscillation when swung as a pendulum. The ball will rotate about 1/2 a revolution from the initial grip to the release point, in about 0.1 sec or less. /R [316 73 572 791 ] As a result of the transfer of kinetic energy from the bat to the ball, it has increased mass and kinetic energy. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. The result was not a super slow softball spin, neither was it particularly fast. The weight and construction of a bat also affects the bounce factor q, and it affects the time and position of the bat at which the swing speed is a maximum. If the bat is at rest then we can define the ball speed ratio, Bounce Factor = q = (ball exit speed) / (incident ball speed). The frequency is typically between 1000 Hz and 2500 Hz, meaning that the wall vibrates in and out 1000 to 2500 times in one second. Functional cookies help to perform certain functionalities like sharing the content of the website on social media platforms, collect feedbacks, and other third-party features. There is a significant difference between end-load and balanced softball bats in terms of weight distribution. Collisions.- 11.Bat Performance.- 12. When a ball is hit in the sweet spot, the collision of the bat and ball creates a compression wave which travels through the bat and is then transferred to the ball, causing it to travel further. There is a greater amount of strength required to swing a wood bat, but the ball exits faster when hit. /I << /R [316 73 572 791 ] The sweet spot is found on only one side of the bat. /Width 77 ] I tossed a 12 inch softball at very low speed and filmed the result, using two hands instead of one to increase the spin rate and to make sure the spin axis was horizontal. 22 0 obj Two ounces doesnt seem like much but Ive seen it make a large difference. /P 23 0 R The answer depends on how fast each bat can be swung. Reflexes. Furthermore, the tip is the lightest and least effective part of the bat. However, there are many variables in experiments like these. ** A new article on knuckleballs was added in May 2013 **. The physics of the three sweet spots of a baseball bat is discussed and the location of the ball impact point on the bat that leads to maximum ''power'' (greatest batted ball speed) is determined. These are effectively the same as the vibrations that travel through the air and reach your ear, where you hear them as sounds. Adding to that is the fact that, When a ball player hits the ball with the bat, it produces an enormous amount of force on the bat in a split second the impact could mean up to. This is due to the fact that the collision is able to create a larger transfer of energy when the bat and ball are in perfect alignment. Baseball is based on the principles of Newtons laws of motion. A first guess would be at the tip of the bat since the tip travels the fastest. For the purposes of this paper, I will attempt to examine the . A batsman during a cricket game aiming his shot to hit the sweet spot of the bat. endobj Bats and Balls.- 3. Performance cookies are used to understand and analyze the key performance indexes of the website which helps in delivering a better user experience for the visitors. The COR for the impact on the granite block is about 0.59 in the low speed collision here, but can be as low as 0.45 in a 100 mph collision. 10 0 obj The spot is close to the centre of percussion (COP) for a freely supported bat, so it was thought at one time that the sweet spot might be associated with the COP. 28 0 obj At the major league level, maple bats now account for 75% to 80% of all bats. /V 6 0 R When a batter hits a ball, the bat will rebound from the force of the collision. 24 0 obj In this paper, we analyze the effect on the ball-bat model of corking the bat, and investigate the relationship between the sweet spot and different materials. Magnetism is also an important aspect of baseball because bats use magnetite, a magnetic substance found in the body, as a means of internal navigation. When it comes to the distance traveled by a ball, speed and speed at which it sails off the bat are all important factors. The impact of a bat and a ball is still not properly understood. the location where maximum energy is transferred to the ball. Your selection may affect the price of the product. The physics of a baseball bat include the material of the bat, the length, weight, and shape of the bat, and the force of the swing. forms: { Dont store your bat in your garage or trunk of your car, bring it inside. What two factors determine the location of a baseball bat sweet spot? More comparisons can be made by adding more information. /Height 99 Try this: dangle the bat lightly by its knob, then use a baseball to strike the bat moving from top to bottom. If the ball is also mounted as a pendulum, the experiment can also be performed in reverse, by swinging the bat at a stationary ball. A knob and end loaded bat may weigh the same, for instance, but the end loaded bat will have a higher MOI. In case that didnt quite clear it up for you, lets break this down a bit. Additionally, a hard material helps to reduce the amount of vibration that travels through the bat and into the players hands, helping them to maintain control over the bat while swinging. The third law explains what happens to a bat when it strikes a ball. What is the fluid speed in a fire hose with a 9.00 cm diameter carrying 80.0 l of water per second? /R [316 74 572 585 ] << The tangential COR is defined in the same way as the normal COR, but in terms of the horizontal speed of the ball at the contact point rather than the normal (ie vertical) speed of the contact point. >> So, if you make sure the label is up, it means that you will be making contact with the edge of the grain which is the strongest part. /Filter /LZWDecode A ball that strikes the bat does not cause it to vibrate at this point. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. In fact, if the ball strikes the bat exactly on the ``sweet spot'' then the hitter is almost unaware of the collision. 6 0 obj Why dies the bat vibrate inside or outside of the sweet spot? throughout the paper. However, the centripetal force does not act along the axis of the bat, but at an angle, as shown by the orange lines. , 231-232 (2001).
