What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as from chemical energy to thermal energy.

What is the law of conservation of energy?

Back

The law of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.

What energy transformation occurs when you light a match?

Back

Chemical energy is transformed into light and thermal energy.

Front

What energy transformations occur in a hand generator?

Back

Mechanical energy is transformed into electrical energy, which is then transformed into light energy.

Front

What energy transformation occurs in a toaster?

Back

Electrical energy is transformed into thermal energy.

Front

What is mechanical energy?

Back

Mechanical energy is the sum of potential and kinetic energy in an object that is used to do work.

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 atoms and molecules.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, depending on its mass and velocity.
