Define Work Done By A Force And Give Some Examples Of It

The work done by a force can be defined as the product of the displacement of an object and the component of the applied force which is in the direction of the object’s displacement. The mathematical expression for the work done by a force F is – W = F.d = (F cosθ)*d (where ‘d’ denotes the displacement of the object upon which the force is applied). The SI unit of work is the Joule, which can be defined as the amount of work done when a force of 1 Newton is applied to an object, as a result of which, it is displaced by 1 metre.
