Question

A ball when rolled on the floor comes to halt at a point by itself due to

1.absence of frictional force

2.presence of frictional force in the same direction as the direction of the motion of the ball

3.presence of frictional force in the opposite direction as the direction of the motion of the ball

4.presence of frictional force in both directions as the direction of the motion of the ball
​

Answer 1

Answer:

The force of friction acts between the two surfaces by opposing the relative motion of one surface over the other. For example, when the ball rolls on the ground, the force of friction acts between the surface of the ball and the surface of the ground.
