work is done when a force is applied to an object and the object is moved from a distance.
joule is the standard unit of energy. it is defined as the amount of work done on a body by a one newton force that moves the body over a distance of 1 meter.

Hey there!
Question -: When is work said to be done? What is 1 joule?
Answer -: Work is said to be done when a body is displaced on the application of a force.
#If the angle between force & displacement is 0° then, W = F*S (positive work)
#If the angle between the force and displacement is 90° then, W = 0
#If the angle between the force and displacement is 180° then, W = - F*S (negative work)
The SI unit of work is Joule whereas the CGS unit of work is erg.
Relationship between the SI & CGS unit of work -:
1 Joule = 10^7 erg
One Joule -:
If ONE NEWTON FORCE is applied to produce a DISPLACEMENT of ONE METRE, then Work Done is said to be One Joule.
