Assertion: When a sphere rolls down an inclined plane without slipping, its kinetic energy is partly translational and partly rotational in nature.
Reason: When a sphere rolls down an inclined plane without slipping, it possesses both translational and rotational motions.

View answer and explanation

Correct option: A

If both assertion and reason are true and reason is the correct explanation of the assertion

Option A is correct because when a sphere rolls down an inclined plane without slipping, it has both translational and rotational motion, and thus its kinetic energy is partly translational and partly rotational.
