Work done (Edexcel GCSE Physics): Flashcards

$W = Fs$

Joules ($J$)

Newtons ($N$)

Distance moved along line of action of force

Energy transferred from object doing work to another form

Work done when $1N$ force causes $1m$ displacement

Rise in temperature of object

W = rac{1}{2}kx^2

Elastic potential energy

Change in shape of object due to applied forces

Object returns to original shape after force removed

Object doesn't return to original shape; permanent change

More than one force

Opposite directions on either side

$1$ newton-metre
