+# Summary
+* Net force equals $\vec F_{net}=\frac{\Delta \vec p}{\Delta t}$
+* Impulse is average force over time interval: $\vec J = \vec F_{avg}\Delta t$
+* Impulse-momentum theory is impulse = change in momentum: $$\vec J=\Delta \vec p = \vec p-\vec p_0$$
+* Integral of a force vs time graph equals impulse, slope of momentum vs time graph = net force
+* Impulse units are N * s (kg * m/s)
+* When mass is constant F=ma comes from Impulse-Momentum theory
