Question

What Is Rotational Kinetic 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. Looking at rotational energy separately around an object's axis of rotation, the following dependence on the object's moment of inertia is observed:

{\displaystyle E_{\mathrm {rotational} }={\frac {1}{2}}I\omega ^{2}}E_{\mathrm {rotational} }={\frac {1}{2}}I\omega ^{2}

where

{\displaystyle \omega \ }\omega \ is the angular velocity

{\displaystyle I\ }I\ is the moment of inertia around the axis of rotation

{\displaystyle E\ }E\ is the kinetic energy
