Which statement best describes the relationship between $\mathrm{energy}$ and $\mathrm{work}$ in physics?

• A. $\mathrm{Work}$ is the process of transferring $\mathrm{energy}$ from one object or system to another.
• B. $\mathrm{Energy}$ is always greater than $\mathrm{work}$ in any physical process.
• C. $\mathrm{Energy}$ and $\mathrm{work}$ are completely unrelated physical quantities.
• D. $\mathrm{Work}$ is a type of $\mathrm{energy}$ that cannot be transferred.

Answer: (A)

Verified step by step guidance

1. Understand the definitions: Energy is the capacity to do work, while work is the process of energy transfer caused by a force acting over a distance.
2. Recognize that work involves transferring energy from one object or system to another, meaning work is not a form of energy itself but a mechanism for energy transfer.
3. Recall the work-energy theorem, which states that the net work done on an object equals the change in its kinetic energy, linking work directly to changes in energy.
4. Evaluate the given statements by comparing them to these concepts: work is not a type of energy, energy is not always greater than work, and energy and work are definitely related.
5. Conclude that the best description is that work is the process of transferring energy between objects or systems.
