What energy transformation occurs in a flashlight?

Back

Chemical energy (from batteries) is transformed into electrical energy, which is then transformed into light energy.

Front

What is an example of mechanical energy?

Back

Mechanical energy is the energy associated with the motion and position of an object, such as a moving car.

What happens to energy when a candle burns?

Back

When a candle burns, chemical energy is transformed into light energy and thermal energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, which depends on its mass and speed.

Front

What is potential energy?

Back

Potential energy is stored energy based on an object's position or state, such as a rock at the top of a hill.
