A sphere is rolled on a rough horizontal surface. It gradually slows down and stops. The force of friction tries to

A

increase the angualr velocity

B

decrease the angualr velocity

C

increase the linear momentum

D

decrease the linear velocity

Text Solution

Verified by Experts

The correct Answer is:
A, D
Force of friction produces the torque for rotation. Therefore, it tries to increase the angualr velocity. However, friction opposes the motion. Therefore, it tries to decrease the linear velocity.
