# Two Billiard Balls Of Equal Mass Undergo A Perfectly Elastic Head-on Collision.

A billiard ball is an interesting piece of equipment to have on hand. They can make a variety of handy products, from water bottles that fit your hands to tables that fit your needs.

Billiards are similar to tennis but with a smaller court and more strategy than just hitting the ball down the line. There are three main balls used in billiards: the golf ball, the racket and the table cloth.

The racket is used to hold and manipulate the different materials during a game. The tablecloth can be used for training or decoration purposes as well.

In this article, we will discuss how to make some easy, mass-changing billiards tools.

## Calculate the momentum of each ball immediately after the collision

When two objects of equal mass but different sizes collide, there is a chance that one of the smaller objects will gain some momentum after the collision. This momentum can go into a roll, roll or bounce.

If you were to roll one of these balls in a circle, it would probably roll in a circle until it stopped or was outpowered by another ball.

This is what happens when an object with less mass rolls faster than an object with more mass. The lighter object will win out and retain its shape as it rolls over the other piece.

By calculating the momentum of each ball before and after the collision, you can know if one of them lost some mass in the collision or not.

## Calculate the mass of each ball

When two objects of approximately the same mass meet, they may undergo a phenomenon known as elastic recoil. This occurs when two objects are struck together in a gymnasium, or when two people shake hands.

When one object is larger than the other, it rebounds with greater force. This phenomenon is similar to how artillery units fire shots in unison rather than one after another.

If you were to shake one of these balls hard, it would take several seconds for the second ball to re-coil like this. It takes more effort on your part to do this and create an even bigger impact!

The process happens very quickly though, so don’t bother trying this after nightfall or if you are feeling drunk. You would be wasting valuable energy since you must wait for the effect to fully happen.

## Explain why it is important to know the mass of each ball

There are two main reasons to know the mass of each ball. The first is in order to prevent two balls from coming together with a perfectly elastic head-on collision. The second is in order to know how much force is required to make one ball move and the other ball change its position.

In a four-way division championship, for example, if one of the top two players lose their temper and slug it out with their opponent, that opponent might get carried away and attack another opponent without thinking.

That could lead to one of them getting hurt or even killed!

It’s important for these kinds of matches to be played under a lot of pressure, so if one guy loses his temper, he can’t accidentally hurt or kill someone else.

## What happens to the kinetic energy?

When a ball is thrown, it has to be maintained at its initial velocity. If the ball slows down or stops moving, it has lost energy!

The same occurs when a person is hit with an object. The energy must be preserved as the body forces the object out and back into its original position.

A billiard ball has only one place to retain its energy while in motion- inside the billiard ball. When an object strikes the outside of a billiard ball, there is a chance that some of the energy may escape through that opening.

This can happen with little or heavy objects. It depends on how hard they were struck and whether or not they were metal or wood.
