Explain what energy changes a cure as water moves through a hydroelectric dam
As water moves through a hydroelectric dam, it undergoes several energy changes. Initially, the potential energy of the water stored in the reservoir behind the dam is converted into kinetic energy as the water flows down through the dam's penstock.
Next, the kinetic energy of the flowing water is used to turn the blades of a turbine, which is connected to a generator. This mechanical energy is then converted into electrical energy by the generator. The electrical energy produced is transmitted through power lines to homes and businesses for use.
Overall, the energy changes that occur as water moves through a hydroelectric dam involve the conversion of potential energy into kinetic energy, mechanical energy, and finally electrical energy. This process allows for the generation of clean and renewable electricity from flowing water.
