EVERYDAY SCIENCE

Detailed explanation-1: -(Answer: The dams hold back large amounts of water. The water is higher than the turbines so it has potential energy. As the water moves downward to the turbines, its potential energy is transformed to kinetic energy, turning the blades of the turbine.)

Detailed explanation-2: -Water gains potential energy just before it spills over the top of a dam or flows down a hill. The potential energy is converted into kinetic energy as water flows downhill. The water can be used to turn the blades of a turbine to generate electricity, which is distributed to the power plant’s customers.

Detailed explanation-3: -m is the mass of water, g is the acceleration due to gravity, and h is the height of the waterfall. Let’s express the kinetic energy of water as a function of mass. This expression means that each kg of water that falls, gains 1960 joules of kinetic energy.

Detailed explanation-4: -What is Hydropower? Hydropower, or hydroelectric power, is one of the oldest and largest sources of renewable energy, which uses the natural flow of moving water to generate electricity.

Detailed explanation-5: -Another example of the change between kinetic and potential energy is a waterfall. A waterfall has both potential and kinetic energy. The water at the top of a waterfall has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy.
