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 |
||
|
\( \Delta L \;=\; \tau_n \cdot \Delta t \) (Change in Angular Momentum) \( \tau_n \;=\; \dfrac{ \Delta L }{ \Delta t }\) \( \Delta t \;=\; \dfrac{ \Delta L }{ \tau_n }\) |

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