Answer:
Kinetic energy.
Step-by-step explanation:
- There are many kinds of energy. Some of them are kinetic energy, potential energy, thermal energy etc.
- The energy that shows the motion of the object is called its kinetic energy.
- Also, the sum of kinetic energy and the gravitational potential energy is called mechanical energy.
- Out of the given options, kinetic energy is the form of energy that represents the motion of the molecules which make up an object.
- Hence, the correct option is (B).
