Work formula: To derive the formula for work

To derive the formula for work done, we’ll start with the basic definition and then connect it to the change in kinetic energy of the object. Work done (W) is defined as the product of the force (F) applied to an object and the displacement (d) of the object in the direction of the force. Work is the energy transferred by a force along a displacement. Learn how work is calculated, measured and understood in physics, with examples and historical background. Learn how to calculate work done by a constant or variable force, and how work is related to energy and power. See solved problems and applications of work -energy theorem in everyday life. Defining Work The scientific definition of work is different in many ways from its everyday meaning. The definition of work in physics reveals its relationship to energy – whenever work is done, energy is transferred. For a work to be done, in a scientific sense, a force must be exerted, and there must be displacement in the direction of the force. With this said, we can say that Work is the product of the component of the force in the direction of the displacement and the magnitude of ...
