What is defined as "Doing Work"?

The concept of "Doing Work" is closely associated with the definition of energy. In physics, work is defined as the process of energy transfer that occurs when an object is moved over a distance by an external force. Specifically, work is calculated as the product of the force applied to an object and the distance over which that force is applied in the direction of the force.

Energy encompasses the capacity to do work. When work is done on an object, energy is transferred to or from that object, which can lead to changes in its state, such as movement or temperature changes. Therefore, energy is the fundamental quantity that represents "doing work."

This makes it clear why energy is the correct response in relation to the question posed about what defines "Doing Work."
