Answer:
Work is a measure of the energy transferred and required a force acting on an object and displacement of the object
Step-by-step 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
![W=Fd cos \theta](https://img.qammunity.org/2020/formulas/physics/middle-school/2dgvcpiyukmn9k9an5vso7g9zjpphs2xfo.png)
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,
.
