Work done in moving a body is equal to the product of force and the displacement of the body in the direction of force.
If a force F acts on an object and s is a displacement of the object in a direction of force then
Work done= Force × Displacement
W= F× s
When a force of 1 newton moves an object through a distance of 1 m in its own direction then the work done is known as 1 J.
1 joule= 1 newton × 1 metre
1 J = 1 N m.
The S.I unit of work is joule.

Hey there!
Work is defined as scalar product of force and displacement.
The expression for the work done when a force is acting on an object in the direction of its displacement is as follows:
W = F . S
where,
F = magnitude of force
S = displacement
1 joule is defined as the the work done when a force of 1 N displaces an object at a distance of 1 m.
