(c) Work and power

Know and use work done = force × distance moved in the force direction, W = Fd.

Know that work done is equal to energy transferred

Know and use gravitational potential energy = mass × gravitational field strength × height, GPE = mgh.

Know and use kinetic energy = ½ × mass × speed², KE = ½mv².

Understand how conservation of energy produces a link between gravitational potential energy, kinetic energy and work

Describe power as the rate of transfer of energy or the rate of doing work

Use power = work done (energy transferred) ÷ time taken, P = W/t.
