Rotational Kinetic Energy Formula
Rotational Kinetic Energy describes the energy posed due to the rotational motion of an object around an axis. The Formula to calculate rotational kinetic energy of an object is given below:
KR = 1/2Iω2
Where,
- KR is the Rotational Kinetic energy,
- I is the moment of inertia,
- ω is the angular velocity.
Rotational kinetic energy is directly proportional to moment of inertia and the square of the angular velocity. This means that if either the moment of inertia or the square of the angular velocity increases, the rotational kinetic energy will also increase accordingly.
