# What are the physics of hitting a baseball?

## What type of kinetic energy is hitting a baseball?

In the fraction of a second that the ball collides with the swinging bat, the ball compresses as the energy of the motion goes into deforming the ball and transforms into into elastic potential energy. This potential energy is transformed into kinetic energy as the ball leaves the bat.

## Is it scientifically possible to hit a baseball?

At the highest levels, hitting a baseball is a seemingly impossible task. Once it leaves the pitcher’s hand, the ball, typically traveling 85 to 95 mph, takes 400 to 500 milliseconds to reach home.

## How much force is a baseball hit with?

Boston White Sox. “The batter exerts some 6000-8000 pounds of force on the ball. 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 it’s size.”

## How do you find the acceleration of a baseball?

1. a=v2−v1t .
2. v1 is the initial velocity,
3. v2 is the final velocity and.
4. t is the time taken (or the time interval in which velocity changes from initial velocity to the final velocity)
5. t=0.238s.
6. a=41−00.238ms−2.

## Is a bat hitting a baseball an example of a collision?

Is hitting a baseball considered an elastic collision? The collision of the bat and the ball is elastic in physics. An elastic collision occurs when the total kinetic energy and the total momentum of two objects are the same before and after the collision. Swinging a bat is labour.

## Is hitting a baseball mechanical energy?

A moving baseball possesses mechanical energy due to both its high speed (kinetic energy) and its vertical position above the ground (gravitational potential energy).

## How conservation of mechanical energy takes place in hitting a baseball?

Complete answer: Energy is transferred within/between different systems. The input energy is transferred through the system and energy is conserved. This means that in the universe the energy is never lost. If the baseball is hit by a bat, the energy transfer from only the bat to the base ball does not take place.

## What energy is when they go when the ball gets thrown or you run real quick to get home?

Kinetic energy depends on an object’s mass and its speed. Ignoring frictional losses, the total amount of energy is conserved. For a rolling object, kinetic energy is split into two types: translational (motion in a straight line) and rotational (spinning).

## What sport is hardest?

Boxing. The Sweet Science. That’s the sport that demands the most from the athletes who compete in it. It’s harder than football, harder than baseball, harder than basketball, harder than hockey or soccer or cycling or skiing or fishing or billiards or any other of the 60 sports we rated.

## How much force does a 90 mph baseball have?

For a 90 mph pitch (40.2 m/s), the ball’s energy needs to be 117.4 joules.

## What makes hitting a major league fastball seemingly impossible?

So why is that the case? For one, the physics are extreme. The velocity of the average fastball in the Major Leagues is more than 90 miles per hour. When the ball whizzes in at that speed from less than 60 feet away, the hitter has about 150 milliseconds to decide whether they want to swing.

## What is the effect of force when a ball is hit with a bat?

The huge force exerted by the bat on the ball causes severe distortion of the ball as it is hit. So, during the bat-ball collision, an average force of roughly two tons acts during the 0.7 millisecond contact time, with a peak force of about four tons. That’s a lot of force!

## How do u calculate force?

Force exerted by an object equals mass times acceleration of that object: F = m * a .

## How many joules is a baseball hit?

Baseballs – heavier than a tennis ball, but not as heavy as a hockey puck – weigh just under 150 grams and have an average velocity of over 46 meters per second. This generates close to 162 joules of energy.

## How do you calculate acceleration?

Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt. This allows you to measure how fast velocity changes in meters per second squared (m/s^2). Acceleration is also a vector quantity, so it includes both magnitude and direction. Created by Sal Khan.

## What is the formula of mass and acceleration?

For a constant mass, force equals mass times acceleration.” This is written in mathematical form as F = ma. F is force, m is mass and a is acceleration. The math behind this is quite simple. If you double the force, you double the acceleration, but if you double the mass, you cut the acceleration in half.

## What is the acceleration of a baseball as it returns to the ground?

The cause of the ball’s acceleration is gravity. The entire time the ball is in the air, its acceleration is 9.8 m/s2 down provided this occurs on the surface of the Earth. Note that the acceleration can be either 9.8 m/s2 or -9.8 m/s2.

## What kind of collision is a baseball bat hitting a baseball?

In physics the collision of the bat and the ball is considered elastic. An elastic collision between two objects is one in which the total kinetic energy and total momentum is the same before and after the collision.

## Is a bat striking a baseball an inelastic collision?

Cars colliding on the road, a bat striking a baseball, a bullet embedding itself in a torso — these are all inelastic collisions. If the objects stick together afterwards, the collision must be inelastic.

## When the baseball bat hits the ball the change in momentum of the bat is?

Answer and Explanation: Impulse is defined as →I=mΔ→v I → = m Δ v → or in other words, the change in momentum. So, when a baseball hits the ball, the impulse delivered to the ball is increased by prolonging the impact. Hence, follow-through increases the impulse.

## What factors affect the energy of a baseball?

The amount of Kinetic Energy that an object possesses is dependent on two factors: mass and velocity. Both of these factors are directly proportional to the kinetic energy.

## What are some examples of mechanical energy?

• Turning a doorknob.
• Breathing in and out.
• Hammering a nail.
• Riding a bicycle.
• Sharpening a pencil.
• Using kitchen appliances.
• Listening to music.
• Typing on a keyboard.

## How is mechanical energy used?

Mechanical energy is produced by sourcing potential and kinetic energy and turning it into power. Examples of this would be steam, water, wind, gas, or liquid fuels that power turbines. Machines are often used to generate other forms of energy through conversion before being used as power.

## What is law of conservation of mechanical energy?

According to the principle of conservation of mechanical energy, The total mechanical energy of a system is conserved i.e., the energy can neither be created nor be destroyed; it can only be internally converted from one form to another if the forces doing work on the system are conservative in nature.
