Which term means the capacity to perform work?

• A. Power
• B. Energy
• C. Charge
• D. Force

Answer: (B)

Energy is the capacity to perform work. Work happens when a force moves something over a distance, and energy is what provides the ability to cause that change. Different forms of energy—kinetic, potential, chemical, electrical—store this ability and can be transformed to do work in various situations. Power would describe how quickly that work is done, not the overall capacity. Charge is a property related to electrical interactions, not a general measure of how much work can be done. Force is the push or pull that can cause motion, but by itself it doesn’t quantify the amount of workic energy available to perform work.
