know and use the relationship between work done, force and distance moved in the direction of the force:

work done = force × distance moved

$W = F × d$

know that work done is equal to energy transferred

know and use the relationship between gravitational potential energy, mass, gravitational field strength and height:

gravitational potential energy = mass × gravitational field strength × height

$GPE = m × g × h$

know and use the relationship:

kinetic energy = 0.5 × mass × speed²

$KE = \dfrac{1}{2} × m × v^2$

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 the relationship between power, work done (energy transferred) and time taken:

$\text{power} = \dfrac{\text{work done}}{\text{time taken}}$

$P = \dfrac{W}{t}$
