In summary, K.E. stands for Kinetic Energy and is the energy that enables billiard balls to move and collide with each other on a pool table. It is calculated using the formula: K.E. = 1/2 * mass * velocity^2 and is affected by the size of the ball, its mass, velocity, and angle of collision. K.E. is conserved in a game of billiards according to the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed.

The question is,
Is the K.E. energy conserved during the collision ?
Given Data : Collision is elastic, ball of same mass.
P.S. It is asked if the K.E. is conserved DURING the impact; not before or after it. After the collision & before it, I know the K.E. is conserved.

FAQ: Is K.E. Conserved During an Elastic Collision in Billiard Ball?

What is K.E. in billiard ball?

K.E. stands for Kinetic Energy, which is the energy an object possesses due to its motion. In billiard balls, K.E. is the energy that enables the balls to move and collide with each other on the pool table.

How is K.E. calculated in billiard balls?

K.E. in billiard balls is calculated using the formula: K.E. = 1/2 * mass * velocity^2. Mass is the weight of the ball and velocity is its speed. This formula is used to determine the amount of energy transferred when the balls collide.

Does the size of the billiard ball affect its K.E.?

Yes, the size of the billiard ball does affect its K.E. According to the formula, K.E. is directly proportional to the velocity squared. A larger ball would have a larger mass, meaning it would have a higher K.E. compared to a smaller ball with the same velocity.

What factors can affect the K.E. of a billiard ball?

The K.E. of a billiard ball can be affected by factors such as the mass of the ball, the velocity at which it is moving, and the angle of collision with another ball. Other external factors like air resistance may also play a role in altering the K.E.

How is K.E. conserved in a game of billiards?

K.E. is conserved in a game of billiards according to the law of conservation of energy, which states that energy cannot be created or destroyed, only transferred or transformed. In billiards, the total K.E. of the balls before and after a collision remains the same, although it may be distributed differently among the balls.
