Work 2. In the language of physics, whenever force acting on a body is actually able to move it through some distance in the direction of force, then work is said to be done by the force. The force may act in any direction except perpendicular in the direction of displacement. Hence for work to be done, Following two conditions must be fulfilled: a) A force must be applied b) The applied force must produce a displacement in any direction ex...
