Work : In physics work is defined if force applied on object displaces the object in direc¬tion of force. But in science âWORKâ has another meaning.According to science, a work is said to be done only when a force act onan object which displaces it or which causes the object to move.Therefore the two conditions required to prove that a work is done are :A force should act on an object.The object must be displaced.If any one of the above conditions does not exist, then work is not done.WORK is a scalar quantity, i.e. docx, 119 KB.
