Question

motion of billiard ball is _____​

Answer 1

The ball, as we mentioned above, will have a spin and a sliding motion at the very start. the velocity of P. = rotation velocity at P. i.e. the moment when the sliding ceases and the ball has a pure rolling motion where v = Rω..

if about energy you are asking then it will be kinetic energy . ... explanation.

It will have transferred all of its kinetic energy to the other ball, which will move forward with the same velocity that the cue ball had before the collision. Collisions can only be elastic if the masses are equal. The masses of billiard balls are the same, which can make some collisions close to elastic.

Hope it will help u

If it's helpful then mark me as brainiest and thanks me ..

Answer 2

The motion of the billiard ball is a one-dimensional motion.

Explanation:

Motion:

• In physics, motion is the phenomenon in which an object changes its position over time. Motion is mathematically described in terms of displacement, distance, velocity, acceleration, speed and time.

Motion in One Dimension:

• If a particle is moving in a single direction throughout its journey then it is said to be moving in one dimension.

• For example, an ant moving along $X-axis$. Motion is described in terms of displacement $(x)$, time  $(t)$, velocity  $(V)$, and acceleration $(a).$Velocity is the rate of change of displacement and acceleration is the rate of change of velocity.
