1.	Explain briefly, how will you find the work done by a variable force?
Answer» Work done by a variable force\tThe variable force is more commonly encountered than the constant force.\tIf the displacement Dx is small, we can take the force F (x) as approximately constant and the work done is then\tDW =F (x) DxFor total work, we add all work done along small displacements.\xa0
