Work done means energy transferred. So, when work is done, energy is transferred from one energy store to another energy store. Example. The boy lifts the box from the ground to above his head, so chemical potential energy store is transferred mechanically to gravtiational potential energy store.
In science, work is defined as the force needed to move an object a certain distance. The amount of work done per unit of time is called power. Suppose you and a friend are helping a neighbor to reshingle the roof of his home.
Work done is simply just the transfer of energy from one object to another. We say that work is done on an object when a force causes it to move a particular distance.
