# Law of Conservation of Angular Momentum

on . Posted in Classical Mechanics

Law of conservation of angular momentum states the angular moment of a system of particles around a fixed point is conserved if there is no net external torque around that point.

## law of conservation of angular momentum formula

$$\large{ L = I \; \omega }$$
Symbol English Metric
$$\large{ L }$$ = angular momentum (rotational momentum) $$\large{\frac{lbm-ft^2}{sec}}$$ $$\large{\frac{kg-m^2}{s}}$$
$$\large{ \omega }$$  (Greek symbol omega) = angular velocity $$\large{\frac{deg}{sec}}$$ $$\large{\frac{rad}{s}}$$
$$\large{ I }$$ = moment of inertia $$\large{ lbm-ft^2 }$$  $$\large{ kg-m^2 }$$
