## 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%

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
