Energy Transformations

Front

What is energy transformation?

Back

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

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 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 mechanical energy?

Back

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

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.

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.

Front

How does a match burn?

Back

When a match is struck, the friction generates heat, converting the chemical energy in the match into thermal energy and light energy.

Front

What happens when propane gas is burned?

Back

Burning propane gas transforms chemical energy into thermal energy, which can then be converted into mechanical energy.

Front

What energy transformations occur in a flashlight?

Back

In a flashlight, chemical energy from the batteries is transformed into electrical energy, which is then converted into light energy.

Front

What is the role of a battery in a circuit?

Back

A battery provides chemical energy that is transformed into electrical energy when the circuit is closed.
