Work work on a is said to done whenever a foxe acts body and the body moves through distance the the direction of force.. rome Work done by a Constant foxe A a body through a distanc force 'F' displaces a body through a 's' in the direction of the force, then, Work done Force Fs X Dciplacement = when force and displacement are each other inclined to Work done, component of force in the direction of displacement x displacement Fcos x S Fs cos Page No. Work done by a Variable Foxe Suppose F depends a variable fore 't' acts arec's on the magnitude الله x as on of a body the foxe shown by the graph To calculate the work done the displacement can be divided into a large number of small equal displacement ox derplacement dw the + F. Ax During work done is arca a small of the rect. ABCD Adding areas of all the rectangles, we get total work done as, W. F.DX In the lim + the summation approche Face No. Date a defenite integral whore value is equal to the area under the curve. Thus, the total work done is
