1work done
work done = force × distance W=Fs
2Gravitational potential
gravitational potential = mass × height × gravitational field strength Ep=mgh
3Kinetic energy
Kinetic energy = 0.5 mass velocity² Ek=½MV²
4Efficiency
Efficiency = useful energy out ÷ total energy in
5Density
mass ÷ volume e=m/v
6Specific latent heat
specific latent heat = energy ÷ mass L=E/m
7Payback time
payback time = cost ÷ savings per year
8Power
Power = work done ÷ time
9Speed
Speed = distance ÷ time
10Acceleration
Acceleration = change in velocity ÷ time
