Which term describes the ability to do work or cause change?

• A. Volume
• B. Mass
• C. Density
• D. Energy

Answer: (D)

Energy is the ability to do work or cause change. It lets objects move, heat, or react because energy can be transformed from one form to another. Work is the transfer of energy when a force moves something over a distance, and forms like kinetic energy (motion) and potential energy (position) show how energy powers change. Volume, mass, and density describe how much matter there is or how tightly it’s packed, not the capacity to cause change. So energy best fits the description because it directly measures the potential to do work or bring about change.
