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

\( \Delta L \;=\;  \tau_n \cdot \Delta t \)     (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 \( sec \) \( s \)
