What force makes a ball roll?

What force makes a ball roll?

The ball, for instance, will feel the force of gravity pulling it downward, the force of the ground pushing it upward direction it is rolling. Since the force of friction goes against the direction that the ball is moving, that is the force that will cause it to slow down.

What stops a ball from rolling?

When you roll a ball on the ground, the electrons in the atoms on the surface of the ground push against the electrons in the atoms on the surface of your ball that is touching the ground. A rolling ball stops because the surface on which it rolls resists its motion. A rolling ball stops because of friction.

Can a ball roll forever?

The theory of inertia says that an objects inertia will maintain its state of motion. So the ball should roll on forever. The ball only stops rolling because an external force (friction) causes the ball to stop. The more inertia an object has, the harder it is to change its state of motion.
