Force and Motion

Average velocity = displacement / change in time
Acceleration = final velocity - initial velocity / change in time
Acceleration = (final velocity)squared - (initial velocity)squared / 2 x displacement
Displacement = initial velocity x change in time + 1/2 acceleration x (change in time)squared
Centripetal acceleration = (tangential velocity )squared/ radius
Net force = mass x acceleration
Work = force x distance
Torque = force x lever arm
Power = work / time

Pythagorean theorem = (a)squared + (b)squared = (c) squared
Efficiency = Work Output / Work Input     x 100%
