Hi Ashish, Work is the energy required to move an object against a force. Work is equal to the force times the distance the object moves. The SI unit for work is the joule. In the case of a constant force, work is the scalar product of the force acting on an object and the displacement caused by t

Work is said to be done by the applied force if it point of application is displaced. SI unit is joule. If force acts upon the body such that energy of body increases then work done is positive Work done = magnitude of scalar product of force and displacement.
