How to Calculate Rotational Kinetic Energy
What is Rotational Kinetic Energy?
Calculates rotational kinetic energy of spinning objects using moment of inertia and angular velocity.
Formula
KE_rot = 0.5 * I * omega^2
Step-by-Step Guide
- 1Enter moment of inertia
- 2Input angular velocity (rad/s)
- 3Calculate rotational kinetic energy
Worked Examples
Input
I = 2 kg·m², omega = 10 rad/s
Result
KE = 100 joules
