* Force of Gravity: This acts downwards on the ball, pulling it towards the center of the Earth.
* Normal Force: This is an upward force exerted by the floor on the ball, counteracting the force of gravity and keeping the ball from sinking into the floor.
* Friction: This force opposes the ball's motion, slowing it down. Friction is a combination of:
* Rolling Friction: This is the resistance between the ball and the floor as the ball rolls.
* Air Resistance: This is the force exerted by the air on the ball as it moves through it.
* Applied Force (if any): This is the force you initially applied to get the ball rolling.
Here's how these forces work together:
1. You apply a force to the ball, starting it rolling.
2. Gravity pulls the ball down, but the normal force from the floor keeps it from falling through.
3. Friction opposes the ball's motion, slowing it down.
4. Eventually, the friction force overcomes the applied force, and the ball comes to a stop.
The dominant force in this scenario is friction, which causes the ball to slow down and eventually stop.
