Static Equilibrium
-All velocities are zero (no net force)
Dynamic Equilibrium
-Nonzero velocity, but CONSTANT
torque = F*l

l = lever arm
Gravitational Potential Energy near the Earth's surface
U = mgh
Elastic Potential Energy
U = (1/2)k*(dx)^2
Work done by any force other than friction:
W = Fdcos(theta)
W = dK + dU (no friction)

Gives the energy transferred into a system due to a force
Power (P)
-Rate of energy transfer

P = dE/t
P(instantaneous) = Fvcos(theta)
