# Change in Angular Momentum

Written by Jerry Ratzlaff on . Posted in Classical Mechanics

Change in angular momentum, abbreviated as $$\Delta L$$, is the porportion of the average net torque and the time interval the torque is applied to.

### Change in Angular Momentum FORMULA

$$\large{ \Delta L = \tau_n \; \Delta t }$$

Where:

$$\large{ \Delta L }$$ = change in angular momentum

$$\large{ \tau_n }$$  (Greek symbol tau) = net torque

$$\large{ \Delta t }$$ = time differential
