As water moves through a hydroelectric dam, several energy changes occur. Initially, the water possesses gravitational potential energy as it flows from a higher elevation to a lower elevation. This potential energy is converted into kinetic energy as the water gains speed and momentum.
When the water reaches the dam, it is directed through turbines that are connected to generators. As the water flows through the turbines, the kinetic energy of the water is converted into mechanical energy, causing the turbine blades to spin. The spinning turbine then drives the generator, which converts the mechanical energy into electrical energy.
Overall, the energy changes that occur as water moves through a hydroelectric dam involve the conversion of gravitational potential energy into kinetic energy, mechanical energy, and finally electrical energy. This process allows us to harness the power of moving water to generate clean and renewable electricity.
