Rotational energy

—

Idealized classical model in SI units. Check sign conventions and assumptions; not a certified engineering design calculation.

Formula

E=½Iω²

Calculate rotation energy from moment of inertia and angular velocity.

Worked example

Moment of inertia (kg·m²)
2
Angular velocity (rad/s)
10
Rotational energy
100 J

Scope and limitations

Idealized classical model in SI units. Check sign conventions and assumptions; not a certified engineering design calculation.

Inputs are checked for missing values and allowed ranges. A result outside the finite numeric range is not displayed. Rounding affects display, while the calculation uses the model’s numeric precision.

Check your units and assumptions before relying on a result. Changing a label does not convert a currency or physical unit.
