Work is said to be done when a force produces a displacement in the body and acts in any direction except
to the direction of displacement.
Work = Force×Displacement
Work and work done are the same things.
1 unit of work
w = f x s
= 1N x 1m
1J = 1Nm
units of work :-
work done is said to be 1 joule if one N force acting on a body displaces a body through 1 m in its own direction .
