Potential Energy

PE = mgh

Kinetic Energy

KE = ½ m vel²

Kinetic Energy of Rotating Body

Work

Work = Force x Distance = F d

Work with force components

Work = Fx d = F cosθ distance

Power

Efficiency

Momentum

Impulse

Law of Conservation of Momentum

Coefficient of Restitution

e = 1 ; perfectly elastic (bounce off)

0 < e < 1 ; inelastic (bounce off or same direction)

e = 0 ; perfectly inelastic (stuck together)

h If the object is hanging

h = v² / 2g

Normal Acceleration

a_N = v² / r

Tangential Acceleration

a_T = r α

Total Acceleration
