The energy possessed by water in a dam is:
Correct answer: A. Potential energy
- A. Potential energy
- B. Kinetic energy
- C. Electric energy
- D. Heat energy
Explanation
The energy possessed by water in a dam is potential energy.Potential energy is the energy that an object has due to its position or state. In the case of water in a dam, the potential energy is due to the height of the water above the ground. The higher the water is, the more potential energy it has.
