AP Physics Cheat Sheet

KINEMATICS Are there only kinematic variables given/asked for?	FORCES Are there forces, masses or accelerations given/asked for?	ENERGY Are you relating a fall or rise to a speed? Are there springs involved? Is there an elastic collision? Is a potential energy graph given? Is force given as a function of x?	MOMENTUM Is there a collision? Is force given as a function of time?	SIMPLE HARMONIC MOTION Is there a spring or pendulum? Is force proportional to x?
ROTATIONAL KINEMATICS Are there rotational kinematic variables given/asked for? Are RPMs given?	TORQUES Are there forces, masses or accelerations given/asked for with rotations or pivots?	ROTATIONAL ENERGY Are you relating a fall or rise to a speed with something rolling or spinning?	ANGULAR MOMENTUM Is there a collision with something rotating before or after? Is there a collision with a pivot?	UNIVERSAL GRAVITATION Are there planets, suns, asteriods, comets, or orbits?
