Question

1. a ball is rolling on a gym floor. why does it eventually stop moving?

Explanation:

In physics, friction is a force that opposes motion. When the ball rolls on the gym - floor, the frictional force between the ball and the floor acts against its motion. This frictional force continuously dissipates the ball's kinetic energy as heat and other forms of energy, causing the ball to slow down and eventually stop.

Answer:

The ball stops moving because of the frictional force between the ball and the gym - floor which dissipates its kinetic energy.
