Question

Which of the following energies do water stored in a dam and the water flowing from it contain respectively?

• A. water stored in a dam - potential energy, water flowing from a dam - kinetic energy
• B. water stored in a dam - kinetic energy, water flowing from a dam - potential energy
• C. both contain kinetic energy
• D. both contain potential energy

Answer 1

The correct option is A

water stored in a dam - potential energy, water flowing from a dam - kinetic energy

Water stored in a dam is at rest and the energy stored is called as potential energy. Once the water starts flowing, it contains the energy of motion i.e., kinetic energy.
