# Angular impulse

## Definition

The angular impulse created by a (possibly time-varying) torque over a time period is dfefined as the integral of the torque over the time period. In other words, the angular impulse created by a torque $\overline{\tau}(t)$ from time $t = t_1$ to time $t = t_2$ is defined as the integral:

$\int_{t_1}^{t_2} \overline{\tau}(t) \, dt$
