How it works
Fill in the 2 fields above and Rotational Kinetic Energy Calculator calculates the result instantly, recalculating as you change any value. It applies the formula KE = ½ I ω². The math runs locally in your browser — nothing is sent to a server.
Formula
KE = ½ I ω²Examples
- Moment of inertia 2 kg·m², Angular velocity 10 rad/s → Rotational KE: 100 J
