WebScience Class 9 Notes – Work and Energy 1. Work : In physics work is defined if force applied on object displaces the object in direc¬tion of force. Hei-e all three terms force, dis¬placement and direction of force are important W= Force x displacement (force in direction of displacement) Unit of work 1 Joule = 1 Newton. 1 metre 1 J= 1 Nm WebAns: Work is said to be done when a force acts on a body and moves it in the direction of the force. Greater is the force acting on a body and longer is the distance moved by it, larger would be the work done. Mathematically, Work is a product of force F and displacement S in the direction of the force. Thus. Work done = Force x displacement. how old was snow white in disney
