when a force causes an object to move through a distance work is done on the object. So a force does work on an object when the force causes a displacement of the object.
work done =force×distance
W = F s
work done, W , in joules, J|
force, F , in newtons, N
distance, s , in metres
one joule of work is done when a force of one newton causes a displacement of one metre
1 joule = 1 newton - metre
work done against the frictional forces acting on an object causes a rise in the temperature of the object
