Solution

Answer :
Water in a dam rotating a turbine coupled to a generator changes Kinetic energy to electrical energy
Explanation
The water is initially at a certain height, therefore it contains the potential energy.
The potential energy is converted to kinetic energy due to the flow of water
The water contains kinetic energy that hits the turbine blade and moves the turbine which helps to generate electrical energy
