What is renewable energy?

Back

Renewable energy comes from sources that are naturally replenished, such as the Sun, wind, and waves.

Front

What is energy conversion?

Back

Energy conversion is the process of changing energy from one form to another, such as converting chemical energy in food to kinetic energy when we move.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. Any object that is moving has kinetic energy.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state, such as a book on a shelf or water behind a dam.

Front

What is the main source of renewable energy?

Back

The Sun is the primary source of renewable energy, providing solar energy that can be converted into electricity.

Front

What is non-renewable energy?

Back

Non-renewable energy comes from sources that cannot be replenished in a short period, such as fossil fuels.

Front

What is an example of energy conversion that produces heat?

Back

Burning wood in a fireplace converts chemical energy into heat energy.

Front

What is the difference between kinetic and potential energy?

Back

Kinetic energy is the energy of motion, while potential energy is stored energy based on an object's position.
