Everything about Virtual work

Work done by a force to move a particle along a virtual displacement

In mechanics, virtual work arises in the application of the principle of least action to the study of forces and movement of a mechanical system. The work of a force acting on a particle as it moves along a displacement is different for different displacements. Among all the possible displacements that a particle may follow, called virtual displacements, one will minimize the action. This displacement is therefore the displacement followed by the particle according to the principle of least action.The work of a force on a particle along a virtual displacement is known as the virtual work.
