Gravitational potential energy and kinetic energy

What this topic asks you to be able to do

  • derive, from W = Fs, the expression ∆EP = mg∆h giving gravitational potential energy changes within a uniform gravitational field
  • recall ∆EP = mg∆h and use it to find changes in gravitational potential energy in a uniform gravitational field
  • derive the expression for kinetic energy, EK = 1/2 mv², by working from the equations of motion
  • recall and apply EK = 1/2 mv²
