# Change in Angular Momentum

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

$$\large{ \Delta L = \tau_n \; \Delta t }$$
Symbol English Metric
$$\large{ \Delta L }$$ = change in angular momentum  $$\large{\frac{lbm-ft^2}{sec}}$$    $$\large{\frac{kg-m^2}{s}}$$
$$\large{ \tau_n }$$  (Greek symbol tau) = net torque $$\large{ lbf-ft }$$ $$\large{ N-m}$$
$$\large{ \Delta t }$$ = time differential $$\large{ sec }$$ $$\large{ s }$$
