Hint: Work is done when a force acts on an object causing displacement. To calculate the amount of work done we must know three basic quantities i.e. force, displacement and the angle between them.

Complete Solution :
Let us first understand what we mean by work and then define its SI unit.
Basically, work is the transfer of an object along some displacement when force is acted upon. So, more often it is represented as the product of force and displacement.

-More precisely, work is the product of the component of the force in the direction of displacement and the magnitude of this displacement.
\[Work=Force\times Displacement\]
-Unit of work in its basic form is $Kg{{m}^{2}}{{s}^{-2}}$.
-SI unit is J.
-Dimension of work is $M{{L}^{2}}{{T}^{-2}}$.
It is the derived unit in the SI system of units.
-In physics, it is equal to the product of newton and metre i.e. N.m
-In electrical terms, it is equal to one watt second i.e. W.s

So, we can say that:
1 J is the amount of work done when 1 N of force is acted upon an object to move it by 1 m of distance.
\[1J=1N\times 1m\]
So, now as we know,
Work is the transfer of energy thus, 1 J of energy transferred from one place to another 1 J of work done equivalently.

Additional Information:
-The other units of work are foot-pound and erg.
-The factors that could affect work are those on which work is purely dependable i.e. force, displacement and the angle between these vectors.

Note: Do note that work is equivalent or closely related to energy but it is not equal to energy. The work-energy theorem states that the work done on any object is perfectly equal to the change in energy of that object, kinetically.
