Question
starting with water in a lake, which of these shows the correct order of energy changes that occur from beginning to end during electricity production with hydroelectric energy? kinetic energy, electricity, potential energy potential energy, electricity, kinetic energy potential energy, kinetic energy, electricity electricity, kinetic energy, potential energy
In hydroelectric energy production, water in a lake has potential energy due to its height (gravitational potential energy). When the water flows down (e.g., through a dam), this potential energy is converted into kinetic energy (energy of motion). Then, the moving water (kinetic energy) turns turbines, which generate electricity. So the correct order is potential energy, kinetic energy, electricity.
