Which term is defined as the ability to do work and cause change, or the capacity to cause changes in matter?

• A. Force
• B. Melting
• C. Temperature
• D. Energy

Answer: (D)

Energy is the ability to do work or cause a change in matter. Think of it as the capacity to make things happen in the physical world. It isn’t the force itself, and it isn’t a process like melting or a temperature reading. Instead, energy is what enables forces to move objects, change their motion, or transform substances. A simple way to see this is to look at a stretched bow. The bow stores potential energy, and when you release it, that energy becomes kinetic energy in the arrow, which does work on the target by moving it. In another everyday example, a light bulb converts electrical energy into light and heat energy, demonstrating how energy can change forms while driving effects in the environment. Different forms of energy include kinetic energy (motion), potential energy (position), chemical energy (stored in fuels and foods), thermal energy (related to temperature), electrical energy, and more. The key point is that energy is the capacity to cause change or perform work, across all these forms, and it can be transferred or transformed but not created from nothing in an isolated system.
