Work is a measure of the energy transferred and required a force acting on an object and displacement of the object

Explanation:

Work is a measure of the energy transferred to an object when a force is applied to the object.

Mathematically, work is defined as

where

F is the magnitude of the force applied on the object

d is the displacement of the object

is the angle between the direction of F and d

We notice from the formula that:

- When the object is not moving, the displacement is zero, so no work is done

- The work done is maximum when the force is parallel to the displacement, , and zero when the force is perpendicular to the displacement, .
