The Capacity of doing work is called_________?
Correct answer: B. Energy
- A. Work
- B. Energy
- C. Power
- D. Momentum
Explanation
Energy is defined as the capacity of a body or system to do work, and it is measured in joules (J). Power measures how quickly work is done, not the capacity to do it. Students commonly choose power because both power and energy are associated with doing work.

About Work
Work is done when a force produces displacement, with its value determined by the component of force along the displacement. The topic covers positive, negative and zero work, work by variable forces from force-displacement graphs, and the connection between net work and change in kinetic energy.
