Change in Angular Momentum

 

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 \( sec \) \( s \)

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.
