$W = F \times s$

Joules (J)

Newtons (N)

Metres (m)

Line of action of the force

Energy transferred from object doing work to another form

Force of 1 newton causes displacement of 1 metre

1 newton-metre

Rise in temperature of the object

$W = \frac{1}{2}kx^2$

Elastic potential energy

Change in shape of object due to applied forces

Returns to its original shape after force is removed

Does not return to original shape, permanent change

More than one force
