Work done on a body equals change in its _ energy.
Correct answer: D. All of these
- A. Total
- B. Potential
- C. Kinetic
- D. All of these
Explanation
Since the type of work that is being done isn't specified, a body can have either kinetic energy due to motion or potential energy due to its motion; either or both of these energies can be affected depending on how the work is done . The work could affect the total energy of the body where the work done could result in a change in the kinetic and potential energy alternatively a change in heat energy could also be observed. Hence all of these.

About Work-Energy Theorem
The work-energy theorem states that the net work done on an object equals its change in kinetic energy. Questions involve positive and negative work, variable forces and force-displacement graphs, acceleration or deceleration, and the difference between this theorem and conservation of mechanical energy, which also requires attention to potential energy and non-conservative work.
