Which term describes energy in an object due to its motion or position, or both?

• A. Potential energy
• B. Mechanical Energy
• C. Entropy
• D. Chemical energy

Answer: (B)

Mechanical energy describes energy in an object that comes from either motion or position, or both. It encompasses kinetic energy, which is energy of motion, and potential energy, which is energy of position in a field like gravity. So it’s the best fit because it covers both aspects in one term: energy due to movement and energy due to where the object is. For example, a swinging pendulum has kinetic energy when moving and potential energy when raised; the total mechanical energy is the sum of those. In contrast, potential energy alone accounts only for position, kinetic energy only for motion, entropy relates to disorder, and chemical energy is energy stored in chemical bonds.
