There’s frictional force acting on the sphere, which causes it to gradually slow down, and eventually come to a stop.
Answer:
The rate at which velocity changes with respect to a change in time is called. acceleration.
Explanation:
Normal force for the rock because that makes an object stable at its position.
static friction because micro-welts hold its particle on its position so it doesn't change in position by a potential energy. Gravity makes it stay on the ground because its force attraction between an object and the earth.
