In science, the word work has a different meaning than you may be familiar with. The scientific definitionof work is: using a force to move an object a distance (when both the force and the motion of the object are in the same direction.)
One joule is defined as the amount of energy exerted when a force of one newton is applied over a displacement of one meter. One joule is the equivalent of one watt of power radiated or dissipated for one second. In some applications, the British thermal unit (Btu) is used to express energy.

work is done when a force moves an object in the direction of the force.
we say that 1 J is done when a force of 1N makes an object move through a distance of 1m
so W = F*S
J = N*m
so 1J is 1Nm or 1 newton - metre
hope it helps u
