What happens to water in a hydroelectric dam?

Back

In a hydroelectric dam, potential energy of water is transformed into kinetic energy as it falls, which is then transformed into electrical energy.

Front

Define kinetic energy.

Back

Kinetic energy is the energy of an object due to its motion.

Front

Define potential energy.

Back

Potential energy is the stored energy of an object due to its position or state.

What is an example of energy transformation in a light bulb?

Back

In a light bulb, electrical energy is transformed into light energy and thermal energy.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter, often felt as heat.
