May 17, 2024 · Definition of the Work Done. Work done is elaborated in such a way that it includes both forces exerted on the body and the total displacement of the body. This block is preceded by a constant force F. The purpose of this force is to move the body a certain distance d in a straight path in the direction of the force.
Sep 12, 2022 · OpenStax. Learning Objectives. Represent the work done by any force. Evaluate the work done for various forces. In physics, work represents a type of energy. Work is done when a force acts on something that undergoes a displacement from one position to another.
In physics, work is done on an object when energy is transferred to the object. In other words, work is done when a force acts on something that undergoes a displacement from one position to another. Forces can vary as a function of position, and displacements can be along various paths between two points.
The definition of work, W , is below: W = F ⋅ Δ x. The work we need to do to burn the energy in the candy bar is E = 280 cal ⋅ 4184 J / cal = 1.17 MJ .

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.
W= (| F |cosθ)| d | (2) In equation 2 work done is defined as the product of magnitude of displacement d and the component of force in the direction of displacement. We know that the scalar product of two vectors A and B where A makes an angle θ with B is given by. A.B =| A | | B |cosθ.
