Work
Work done on an object is defined as the product of the magnitude of the force acting on the body and the displacement in the direction of the force.
W = F.s
If a force acting on a body causes no displacement, the work done is 0. For example, pushing a wall.
Two conditions need to be satisfied for work to be done:
(i) A force should act on object
(a) The object must be displaced
Work = Force x Displacement
Unit of workdone = Joule = Newton x metre
1 Joule work is said to be done when 1 Newton force is applied on an object and it shows the displacement by 1 meter.
