Expert Answer
Weight: The force with which an object is attracted towards the earth is the weight of that object.
It is written as W = m × g.
The SI unit of weight is newton (N).
Work: Work done in moving a body is equal to the product of force exerted on the body and the distance moved by the body in the direction of force.
It is written as W = Force × Distance.
The SI unit of work is newton metre (N m) or joule (J).
