Energy Transformation Nine Week Review

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as converting electrical energy into light energy.

What happens to electrical energy when a lamp is plugged in?

Back

Electrical energy is transformed into light and thermal energy.

Front

What type of energy transformation occurs in a complete circuit with a battery and buzzer?

Back

Chemical energy is transformed into electrical energy, which is then transformed into sound energy.

Front

What does the law of conservation of energy state?

Back

The law of conservation of energy states that energy can neither be created nor destroyed; it can only change forms.

When a bear eats a fish, what type of energy transformation occurs when it runs away?

Back

The bear's body converts chemical energy from the food into mechanical energy for movement.

Front

What energy transformations occur when a candle is lit in a paper lantern?

Back

Chemical energy from the candle is transformed into thermal energy (heat) and then into kinetic energy (lifting the lantern).

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.

Front

What is thermal energy?

Back

Thermal energy is the energy that comes from the temperature of matter; it is the total kinetic energy of particles in an object.

Front

What is chemical energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like food or fuel.

Front

What is light energy?

Back

Light energy is a form of energy that is visible to the human eye and is produced by the vibration of electrically charged particles.
