MCQ
A sphere is rolled on a rough horizontal surface. It gradually slows down and stops. The force of friction tries to:
  • A
    Decrease the linear velocity.
  • B
    Increase the angular velocity.
  • C
    Increase the linear momentum.
  • D
    Decrease the angular velocity.

Answer

  1. Decrease the linear velocity.
  2. Increase the angular velocity.

Explanation:

If a sphere is rolled on a rough horizontal surface, the force of friction tries to oppose the linear motion and favours the angular motion.
