In a hydroelectric dam, the distribution of kinetic and potential energy varies depending on the position of water within the system:
1. **Kinetic Energy**: The kinetic energy of the water is highest at the point where it is released and begins to flow through the turbines. This typically occurs as the water moves from the penstock (the pipe that carries water to the turbines) into the turbines themselves. As the water accelerates due to the force of gravity, its kinetic energy increases.
2. **Potential Energy**: The potential energy of the water is highest at the reservoir or the top of the dam. This is because potential energy is directly related to the elevation of the water; the higher the water, the greater its potential energy due to gravitational potential. As the water is stored at a higher elevation, it has the capability to do work when released.
In summary:
- **Kinetic Energy is highest at the turbines** where the water is flowing rapidly.
- **Potential Energy is highest at the top of the dam** in the reservoir.
