Rotational kinetic energy
Calculate rotational kinetic energy from moment of inertia and angular speed.
Method and scope
Krot = ½Iω².
Use rotational kinetic energy for educational calculation or a clearly scoped arithmetic estimate. Intended for Learners, General educational use.
Inputs- Moment of inertia — kg·m²
- Angular speed — rad/s, rpm
SOURCE AND LIMITS
Assumptions: The body rotates about a fixed axis. The entered moment of inertia is about that same axis.
Limitations: Does not infer moment of inertia from object geometry.
