Question

which of the following is a form of mechanical energy?
a. thermal energy
b. gravitational potential energy
c. nuclear energy
d. chemical energy

Explanation:

Mechanical energy is the sum of kinetic energy and potential energy. Gravitational potential energy is a type of potential energy and thus a form of mechanical energy. Thermal energy is related to heat, nuclear energy is from atomic nuclei, and chemical energy is from chemical bonds, none of which are mechanical energy.

Answer:

B. Gravitational potential energy
