A mass of water above base level in a stream has ________ energy; as it flows downstream, this energy becomes ________ energy.
A) kinetic; potential
B) potential; kinetic
C) kinetic; kinetic
D) potential; potential

Question

Quizplus · Accepted Answer

The mass of water above base level in a stream has potential energy due to its position, and as it flows downstream, this energy is converted into kinetic energy, hence it becomes kinetic energy. Therefore, the best choice is B, potential energy becoming kinetic energy.
