 ## Momentum and impulse
 
 Please see [SL Physics 1#2.4 - Momentum and impulse](/g11/sph3u7/#24-momentum-and-impulse) for more information.
+
+The change of momentum with respect to time is equal to the average force **so long as mass is constant**.
+
+$$\frac{dp}{dt} = \frac{mdv}{dt} + \frac{vdm}{dt}$$
+
+Impulse is actually the change of momentum over time.
+
+$$\vec J = \int^{p_f}_{p_i}d\vec p$$
