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

Work done = force x distance moved


W = F x d


Example...

A tow truck drags a car 5m with a force of 340N, find the work done.

5 x 340 = 1700J

NOTE: Work done is measured in Joules, this is because it is the same as energy transferred (and energy is measured in Joules)
