Energy Formulae summary

Here is a list of all the formula mentioned in this topic:


 








Quantities and Units
  • Energy = Joules (J)
  • Wd = Work done (J)
  • GPE = Gravitational Potential Energy (J)
  • KE = Kinetic Energy (J)
  • F = force (N, Newtons)
  • d = distance moved in the direction of the force (m, metres)
  • m = mass (kg)
  • g = gravitational field strength (N/kg) NB: G on earth = 10N/kg
  • h = height (m)
  • v = velocity (m/s)
  • P = power (W, Watts)
  • t = time (s)
