Which of the following is one of the six energy types listed?

• A. Nuclear energy
• B. Potential energy
• C. Sound energy
• D. Light energy

Answer: (B)

Energy can exist in stored forms as well as in motion, and potential energy is the stored form of energy due to position in a field. In many courses, one of the six common energy types is potential energy, alongside others like kinetic, chemical, electrical, thermal, and radiant energy. This makes potential energy the correct pick because it represents energy stored by where something is or how it’s arranged, rather than energy currently in use. For example, a rock held above the ground has gravitational potential energy, and a stretched spring has elastic potential energy. The other options describe real energy types, but they fit different categories or aren’t listed as the six standard forms in this context.
