+Linear momentum: $$\vec p=m\vec v$$
+$\vec p$ is momentum in kg * m/s
+
+# Summary
+* Momentum: $\vec p=m\vec v$
+* It's a vector
+* Doubling either mass or velocity doubles momentum
+* In one dimension, assign positive and negative signs
+* Collision is an interaction where forces between objects are much larger than net external force on system
+* Explosion is interaction where internal forces push parts of a system apart
