Question

define rotation and energy?
​

Answer 1

Answer:

Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.

Formula

E rotational =1/2× I × omega^{2}

E rotational = rotational energy

I = moment of inertia around the axis of rotation

\omega = angular velocity

Answer 2

Rotation

A rotation is a circular movement of an object around a center of rotation.

Energy

Energy is the capacity for doing work. It may exist in potential, kinetic, thermal, electrical, chemical, nuclear, or other various forms.

OR

Rotational energy or angular kinetic energy is kinetic energy due to the rotation of an object and is part of its total kinetic energy.
