# 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.

## Formulas that use Change in Angular Momentum

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

### Where:

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

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

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