$<b>$ JOULE:-

it is the absolute unit of work in SI named after British physicist James prescott Joule.
" 1 joule of work is said to be done when a force of one Newton displaces a body through a distance of one metre in its own direction."

$1 \: joule = 1 \: newton \times 1 \: metre$

Work:-
work is said to be done whenever a force acts on a body and the body moves through some distance in the direction of the force.

Answer 2

Joule :-



Joule is the SI unit of work done and energy. 1 Joule is equal to the work done by a force of 1 N that causes a displacement of 1 m, that is,

1 Joule = 1 N.m

Joule is named after one of the greatest physicist :- James Prescott Joule.

Work done :-

When there is a displacement in an object by a force acting on it, then the work is said to be done. Work is also equal to the change in energy, that is,

Work done = final kinetic energy - initial kinetic energy or
Work done = final potential energy - initial potential energy.


Energy :-

Capacity of doing work is called as energy.
