Angular Momentum Formula
Formula
L = I × ω
For point mass:
L = m × r² × ω
Where:
- • L = angular momentum (kg⋅m²/s)
- • I = moment of inertia (kg⋅m²)
- • ω = angular velocity (rad/s)
- • m = mass (kg)
- • r = radius (m)
Moment of Inertia Examples
- • Point mass: I = mr²
- • Solid sphere: I = 2mr²/5
- • Solid cylinder: I = mr²/2
- • Thin rod (center): I = ml²/12
- • Thin ring: I = mr²
