Question

Complete the sentence.

The water stored behind the dam represents an example of
energy. As the water flows through the dam at high speed, its energy is converted into
energy due to its motion. The flowing water turns the turbine, converting its energy into mechanical energy as it moves. The rotating turbine powers the generator, which then transforms the mechanical energy into
energy, making it usable for electricity. However, not all energy is fully converted. Some energy is lost at each stage, primarily heat, due to friction.

Answer 1

The water stored behind the dam represents an example of gravitational potential energy. As the water flows through the dam at high speed, its energy is converted into kinetic energy due to its motion. The flowing water turns the turbine, converting its energy into mechanical energy as it moves. The rotating turbine powers the generator, which then transforms the mechanical energy into electrical energy, making it usable for electricity. However, not all energy is fully converted. Some energy is lost at each stage, primarily heat, due to friction.
