|
Static Equilibrium
|
-All velocities are zero (no net force)
|
|
|
Dynamic Equilibrium
|
-Nonzero velocity, but CONSTANT
|
|
|
Torque
|
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) |
