- Elastic potential energy= 0.5 X spring constant
- Q= I x t
- P= W (work done) / t
- E transferred = P X t
- V= I x R
- E transferred= Q x V
- Efficiency = useful power output / total power input
- P = E / t
- Change in thermal energy = mass X shc x temperature change
- Density = mass / volume
- Force = spring constant X extension
- Weight = mass X gravitational field strength
- Work done = force X distance moved
