Answer the following question given this paragraph: To harness water power, a stream must be dammed. Narrow valleys are the best for dams. While sitting in the reservoir behind the dam, the water has potential energy. Water is allowed to flow downhill into a large turbine. While flowing downhill, the water has kinetic energy. Kinetic energy makes the turbine spin. The turbine is connected to a generator, which makes electricity. Q: Water is allowed to flow downhill into a large turbine to harness power. what helps the turbine spin? Choices: - residual energy - electrostatic energy - polar energy - kinetic energy A:
A:
kinetic energy
