Answer 2

$\huge\mathcal{\fcolorbox{lime}{black}{\red{Answer}}}$

Work, in physics, measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement. To express this concept mathematically, the work W is equal to the force f times the distance d, or W = fd. Work is force applied over distance.

Example :-

Examples of work include lifting an object against the Earth's gravitation, driving a car up a hill, and pulling down a captive helium balloon. Work is a mechanical manifestation of energy. The standard unit of work is the joule (J), equivalent to a newton - meter (N · m).
