Kinetic energy
Gravitational potential energy
U = mgh
Elastic potential energy
Total mechanical energy
E = U + K
Conservation of mechanical energy
ΔE = ΔU + ΔK = 0
Work done by nonconservative forces
Wnonconservative = ΔE = ΔU + ΔK
Definition of work (mechanical)
W = F · d = Fd cos θ
Definition of work (isobaric gas–piston system)
W = PΔV
Definition of power
Work–Energy theorem
Wnet = ΔK = Kf – Ki
Mechanical advantage
Efficiency
