Question

Establish relation between angular momentum and rotational Kinetic energy.​

Answer 1

Answer:

when an object is rotating about its center of mass, it's rotational kinetic energy.

when a angular velocity of a sinner wheel doubles, it's kinetic energy increases by a factor of four.

Answer 2

$Answer$

If we push on an object in the forward direction while the object is moving forward, we do positive work on the object. Rotational kinetic energy = ½ moment of inertia * (angular speed)2. ... When the angular velocity of a spinning wheel doubles, its kinetic energy increases by a factor of four.
