Dynamics Dungeon: Newton's Arena

How this connects to AP Physics 1 (Topics 2.3, 2.4, and 2.5): Law 1: an object's velocity changes only when the net force on it is not zero, so zero net force means constant velocity (not "stopped"). Law 2: a = F_net/m, so acceleration is proportional to the net force and inversely proportional to the mass. Law 3: when A pushes on B, B pushes back on A with an equal and opposite force, and because the two objects can have different masses, their accelerations can be very different.
