Angular Momentum Calculator

Find angular momentum from moment of inertia and angular velocity.

Angular momentum (kg·m²/s) 10

Formula: L = I·ω

Step-by-step with your numbers:

1. Values used:

2. Moment of inertia = 2 kg·m²

3. Angular velocity = 5 rad/s

5. Angular momentum = Moment of inertia x Angular velocity = 2 x 5 = 10kg·m²/s

Did we solve your problem today?

Angular momentum is the rotational equivalent of linear momentum.

The math behind it

L = I·ω. It is conserved when no external torque acts — why a spinning skater speeds up by pulling in their arms.

I = 2 kg·m², ω = 5 rad/s → L = 10 kg·m²/s.

Why does a skater spin faster?

Pulling arms in lowers I, so ω rises to conserve L.
