Work and potential energy

Part of the Foundations of Engineering Mechanics book series (FOUNDATIONS)


The sum of the elementary work due to the application of forces F i at points M i of a system undergoing virtual displacements δr i of these points from their positions at a fixed time instant is given by
$$ \delta 'W = \sum\limits_{i = 1}^N {F_i } \cdot\delta r_i .$$
The notation δ’ is used to indicate that we are dealing with an infinitesimal quantity which is not a variation of the quantity W.
