Is rotational...

Question

Is rotational energy a subdivision of mechanical energy?

Open in App

Solution

Rotational energy is the energy due to rotation. It is a form of kinetic energy.
The sum of all energy in a mechanical system is known as the mechanical energy. Mechanical energy includes both kinetic energy and potential energy. Thus, we can say that rotational energy is a subdivision of mechanical energy.
