/R [52 73 308 791 ] The
whole mass of the bat is not involved in the collision, unless the collision
happens to occur at the centre of mass of the bat. Choosing the right wood is essential for the proper performance of baseball bats. /Title (Untitled) To increase the acceleration of the ball while it is still moving, a bat that strikes it harder will most likely accelerate faster. It is not difficult to swing a bat. The ball rotated more than 1/4 but less than 1/2 of one
revolution from one frame to the next, each frame being 0.04 sec apart. A ball that strikes the bat does not cause it to vibrate at this point. A high-end bat is designed for major league hitters in the 31-to-32-ounce (878 to 907 grams) range. ,
231-232 (2001). Preliminary In order to indicate the origin of the baseball bats problem, the following preliminary are worth mentioning. 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. While
the center of mass moves one way (nearly upward here), the handle moves the
opposite way (nearly downward). << 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. Its center of mass is 52.6
cm from the knob end. The first is where the bat feels best in your hands when you hit. It is very surprising that no one seems to have worked this out before. The sweet spots location for maximizing how far the batted ball travels after being hit can be calculated scientifically. A baseball bat is typically between 30-34 inches in length and can weigh anywhere from 24-30 ounces. endobj Similarly, an impact
at the node of the second mode will not excite the second mode but it will
excite the fundamental mode. 6 0 obj 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. Some results for an Easton BK7 aluminum bat are shown
below in 13 QuickTime movie files, each about 1 Mb. 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. When selecting a bat for the major leagues, it is critical for players to select the best wood for their bat in order to maximize performance, durability, and longevity. The softball bat will vibrate mainly because it either hitting or missing the sweet spot. 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. How is this spot and its behavior described in Mechanics? [/CalRGB /R [316 73 572 791 ] The ball is spinning clockwise before it bounces and
hits the granite block with backspin. According to Newtons third law, every action has an equal and opposite reaction. When a pitch is played, a turbulent stream of air runs behind the ball. 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. Newtons second law, which deals with the value of time, is also important in baseball. /R [316 73 572 791 ] /R [316 73 572 791 ] A simple introduction to the physics of the collision problem
is given, Some hoop mode sounds are recorded in the following
QuickTime Movies, using an aluminum bat and several aluminum tubes of various
diameters and wall thickness. Physics; Physics questions and answers; A baseball bat has a "sweet spot" where a ball can be hit with almost effortless transmission of energy. One of the definitions of the "sweet spot" is the location of the node at the barrel end of the bat. /N 6 0 R A 28-inch bat should be ideal for anyone weighing 61 pounds or more who has a height of between 61 and 80 pounds. The sweet spot classification quantifies that as a batted-ball event with a launch angle ranging from 8 to 32 degrees. In the late 1990s, the Crisco-Greenwald Cage Study found that bats made out of materials like aluminum perform better, for a number of reasons: First of all, it takes more skill. << How Many Square Inches Of Orange Does It Take To Cover A Baseball Cap? A bat is essentially a long stick. Physicist Daniel A. Russell explains the physics of a baseball swing with a bat. The second definition is where the ball comes off the bat fastest. On average, the sweet spot occurs between 5 and 7 in (12.7 and 17.8 cm) from the barrel end of the bat. >> 7 0 obj A rough estimate would be that the ball rotates 1/4 revolution
while it is in the pitchers hand. Second, if players started using aluminum bats, every MLB record would be shattered within a year and the statistics of the game would be changed completely. You can actually hear where the sweet spot is just by tapping a bat yourself. It is almost as
easy as walking. The ball bounces backward spinning counter-clockwise. Necessary cookies are absolutely essential for the website to function properly. Washington State University Sports Science Laboratory, You can get into the real nitty gritty of the science of MOI including complex equations by clicking through to the complete Bat-Ball Science Mass Moment of Inertia article, but well put it in laymans terms. The weight drop of a baseball bat is the difference between a bats length and its weight in ounces, which is the difference between a bats length and weight in ounces. 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. q is also called the apparent coefficient of
restitution or ACOR. Wind farms have different impacts on the environment compared to conventional power plants, but similar concerns exist over both the noise produced by the turbine blades and the . Thank you so much for. 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. There is no set formula. QuickTime movie files A and B show a baseball bouncing on a block of granite. >> It is also known as the weight to length ratio. 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. Impact at 2 cm Impact at 7 cm Impact at 12 cm Impact at 17 cm, Impact at 24 cm Impact at 31 cm
Strike
at 2cm Strike at 7 cm. Scientifically speaking, this is the weakest part of a wooden baseball bat. However, it will also feel heavier when swung. /V 19 0 R hitting a baseball is either painful or frustrating. How do you control where to hit a baseball? 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. Baseball is a science that is based on fluid dynamics. /Length 996 A question that is equally interesting is how the
swing speed of each body segment varies as the bat speed varies and as the bat swing
weight varies. If this is the case, the bats likely too heavy if it cant keep its grip in place for at least 20 seconds. This makes the game easier to pick up and more exciting to watch otherwise, every hit would only be a single. /N 9 0 R Published Mar 30, 2018 4:11 PM EDT. Is it possible to hit heavier bats harder? This point, usually 5-7 inches from the barrel end, does not move when the bat is vibrating in its first (or fundamental) bending mode. >> Baseball is a beloved American pastime, with millions of people playing the game recreationally or professionally each year. If there is a force of 5,000lb on the ball then . When you hit a stick off center, two things happen: The entire stick wants to move straight backward, and it also wants to rotate around its center. /R [52 74 308 585 ] A knob and end loaded bat may weigh the same, for instance, but the end loaded bat will have a higher MOI. Take a hammer in the other hand and gently tap the bat at various places along its length. Every sport is governed by the laws of science physics, aerodynamics, kinematics, etc. 13 0 obj If the ball is struck at the sweet spot of the bat, then . Other uncategorized cookies are those that are being analyzed and have not been classified into a category as yet. Some hoop mode sounds are recorded in the following
QuickTime Movies, using an aluminum bat and several aluminum tubes of various

is the lightest and least effective part of the bat. MLB . 1 0 obj 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. However, when
the bat strikes the ball at the dead spot then the ball exit speed = V = speed
of bat just before the collision. But the bat vibrates strongly for
impacts near the tip of the bat and near its center of mass. When you hit a ball just right, you've hit it on one of the three "sweet spots" of the bat. Elastic behaviour in the horizontal direction can be
described by a tangential coefficient of restitution, which is about 0.5 or 0.6
for a superball but only about 0.2 for a baseball on a rigid surface. The following material has been expanded considerably into a 324 page
book Physics of baseball and softball published by Springer in March 2011. The cookie is used to store the user consent for the cookies in the category "Performance". } This is the online home for all things baseball. << endobj 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. 3. /N 16 0 R Wood bats and aluminum bats have their own set of advantages and disadvantages, and the choice for the player is based on preference. By understanding the physics of baseball bats, players can maximize their performance on the field. As such, aluminum baseball bats do not have a fixed point. The material of the bat can affect its performance, as lighter bats tend to be more responsive and have higher exit velocities. 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. 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. 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. 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. We use cookies on our website to give you the most relevant experience by remembering your preferences and repeat visits. To squarely hit a fastball, everything has to . This cookie is set by GDPR Cookie Consent plugin. The flight of a
ball through the air depends strongly on how fast it spins, and in what
direction it spins. That said, composite and metal bats are still used by younger players who are still developing their skills. When one object collides with another, some of the energy from the impact goes into vibrational waves that travel through each object. })(); Designed by Elegant Themes | Powered by WordPress, The Ultimate Guide to Baseball-Themed Online Slot Games, How To Hem Baseball Pants: A Step-by-Step Guide For Customizing Your Look. Is swinging a bat potential or kinetic energy? George Jackson is the founder and lead contributor of Physics Network, a popular blog dedicated to exploring the fascinating world of physics. The lines behind the bat, passing through the axis,
mark out angles of 5, 10, 15, 20, 25 and 30 degrees. The sweet spot of a bat exists because bat vibrations
are not excited significantly at that spot. /Height 99 Each baseball bat has a sweet spot due to vibrational physics. /V 6 0 R It would therefore not be surprising if a softball can be pitched at
say 1000 rpm. Dont store your bat in your garage or trunk of your car, bring it inside. 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. The impact of a bat and a ball is still not properly
understood. /I << The Physics of Baseball. Bat speed depends on MOI, and is an important component of laboratory performance tests. /P 14 0 R The bat breaks when large amplitude vibrations reach the thin part of the handle. 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. If the bat approaches a ball incident at speed v. Are heavy bats are more powerful than light bats? Joe Jackson, a shoeless man, would prefer a custom-built bat known as Black Betsy. /V 12 0 R Share your thoughts with us below! Pitching Trajectories.- 5. The effect of the hands on the centre of percussion is
described in American Journal of Physics, , 622-630 (2004). Bud Hillerich, an apprentice woodworker in Louisville, Kentucky, began making Louisville Slugger bats in 1884. First and foremost, we develop a simple but effective theoretical model to give a rough estimate for the sweet spot of the bat. Join PopSci+ to read sciences greatest stories. There is no simple physics
answer to the heavy/light bat question here. 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. The majority of wooden bats are made from ash, with maple, hickory, and bamboo following in their footsteps. The average hitter needs about 50 milliseconds to instinctively assess the speed and location of an incoming pitch. For a fastball, this wake gets pushed down, which then pushes the ball up .. If a player can maintain the same bat swing speed with a heavier bat, the heavier bat will produce higher batted ball velocity and an increase in distance. When a batter hits a ball, the bat will rebound from the force of the collision. /N 10 0 R The bat slows down after the collision (bat speed approximately cut in half), but the bat continues to rotate as a rigid object with no vibration. not apply to baseball or softball bats. Baseball bats are most commonly made out of wood, such as maple, ash, or bamboo. /N 18 0 R Contacting the Ball.- 8. 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. This website uses cookies to improve your experience while you navigate through the website. Near the end of the swing, the force is roughly at right angles to
motion of the handle since the centripetal force is very large. That should sound like more of a thud, because youre not hearing the vibrations inside the wood. Both papers can be downloaded here and here. A bat is similar to a racquet but there are some obvious
differences. 25 0 obj 2.1. Any two connected segments can be analysed as a double
pendulum. 2 5 8 on a bat simply refers to the weight of the bat in ounces. Through its shape, weight, and material composition, a baseball bat is designed to maximize a players power and accuracy while theyre at the plate. If the ball is at rest (when striking a ball off a
T ) then. However, there are many variables in experiments
like these. The answer
depends on how fast each bat can be swung. The result: a harder-hit ball. So, why does the MLB still use wooden bats? endobj This is not an easy rating to obtain. Though all of this means that us amateurs dont want to have batting practice for more than 10 minutes, it does help you train. 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. The reversal of
the spin in each bounce implies that there is some tangential elastic behaviour
of the ball in a direction parallel to the block. However, it will also feel heavier when swung. The physics behind this phenomenon involves the transfer of energy from the bat to the ball. Strike at 12 cm Strike at 17 cm Strike at 24 cm Strike at 31 cm. As discussed earlier, missing the sweet spot can cause vibrations in the bat. Alan Nathan has the world's best Physics of Baseball
site at http://go.illinois.edu/physicsofbaseball, Another very interesting Physics of Baseball and
Softball site is maintained by Dan Russell at http://www.kettering.edu/~drussell. We offer our conclusions in Section 6. Bats and Balls.- 3. /R [52 73 308 791 ] 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. 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. 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. A bat with an end loaded weight indicates that it weighs between 30 and 28 ounces. The faster the hit ball travels, the longer it should travel. Only a small fraction of that huge force gets back to the handle to trouble the batter. . 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. 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. /V 5 0 R Experience. /R [52 73 308 791 ] The sweet spot of a bat exists because bat vibrations
are not excited significantly at that spot. Each type of wood has its own unique characteristics, making it important for players to consider the type of wood when selecting a bat. 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 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. The
bounce was filmed at 300 fps and is played back at 30 fps in slow motion. Rather, the
physics depends more on the ratio of the bat and ball speeds, regardless of
whether the actual speeds are around 1 mph or 100 mph. It's where the wood grain is strongest. 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. The outgoing speed of the ball is just the sum of the two separate parts
- the speed when the bat is at rest plus the speed when the ball is at rest. A bat that is too light also hampers the development of a solid, level swing. The bat was swung through
an angle of about 30 degrees to strike the ball. Since the CM traces out a spiral rather than a circular
path, the center of the circle moves, as the bat is swung, along the path traced out by the inner
circle of black dots. These spots are also described in the physics of
tennis page. The cookie is used to store the user consent for the cookies in the category "Analytics". 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 bat was swung through an axis 143 mm from the knob
end. The bat is 84 cm long, and has a mass of 849 gram. It's this tendency to rotate that makes the bat's handle push back on or pull out of your hands. 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 . The ball rotated more than 1/4 but less than 1/2 of one
revolution from one frame to the next, each frame being 0.04 sec apart. ** A new article on knuckleballs
was added in May 2013 **. << 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. Thick
walls are also needed to help prevent the walls dinting or cracking. The player will swing the bat from low to high, with too much bat speed resulting in fly balls. They have a hoop vibration mode - alongside the typical bending modes - that extends their sweet spots. 10 0 obj This area is a product of physics, as the sweet spot is located at the center of percussion, which is the point on the bat that produces the least amount of vibration when hit. In general, swing weight increases
with actual weight, but swing
weight also depends on bat length and weight distribution. Image by Pulkit Sinha Own work. When you use a heavier bat, the faster you hit the ball, the longer it will travel. These modes are shown in the diagram above. While the majority of baseball bats are constructed from wood, there are also metal alloy bats available for certain leagues. He is a proud supporter of his local team, the Toronto Blue Jays, and loves to explore the history and culture of the sport. It was found, by
measuring the frequencies of lots of aluminum tubes (see photo) that the frequency is directly
proportional to the wall thickness and inversely proportional to the tube
diameter squared. Try this: dangle the bat lightly by its knob, then use a baseball to strike the bat moving from top to bottom. What is the biggest problem with wind turbines? The diagram below shows the swing of a wood bat filmed from a spot
above the batters head. Specifically, what forces and torques are exerted on the handle,
and in what directions do they act? A homerun hit right at the sweet spot would sound different than one hit off the target. We and our partners use cookies to Store and/or access information on a device. /N 22 0 R >> /R [316 73 572 791 ] /V 24 0 R 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. These cookies help provide information on metrics the number of visitors, bounce rate, traffic source, etc. In
theory, the ball bounces best for an impact at the center of mass of the bat,
provided we can ignore bat vibrations. That is, a large fraction of the
stored elastic energy in the wall is retained as vibrational energy in the bat. These are effectively the same as the vibrations that travel through the air and reach your ear, where you hear them as sounds. I have done quite a bit of independent research in both areas.
