With Cuemath, find solutions in simple and easy steps.īook a Free Trial Class Examples Using Formula For WorkĮxample 1: 10 Newton of force is applied on a body which displaces it by 2 meters. Use our free online calculator to solve challenging questions. Now, if the effective component of force along the direction of displacement is Fcosθ responsible for the displacement of any object in the given direction, then work done by the force F in displacing the body through displacement d is, W=(|F|cosθ)|d| Since F = ma (Newton's 2nd law), thus W = Fs. In general, the work done by force F is equal to the change in kinetic energy If 1 joule of work is done then the formula for work comes out to be 1 J = 1 N.m Derivation of Work FormulaĬonsider a block placed on a frictionless horizontal floor acted upon by a constant force F due to which this block moves through a distance d in a straight line in the direction of the force.
