Energy Types

Front

What is Chemical Energy?

Back

Chemical energy is the energy stored in the bonds of chemical compounds, like atoms and molecules. It is released or absorbed during a chemical reaction. Example: Food contains chemical energy that our bodies use.

Front

What is Mechanical Energy?

Back

Mechanical energy is the sum of potential energy and kinetic energy in an object. It is the energy associated with the motion and position of an object. Example: A moving car has mechanical energy.

Front

What is Electrical Energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices and appliances. Example: Lightning is a natural form of electrical energy.

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. Example: The heat from a fire is thermal energy.

Front

What is Radiant Energy?

Back

Radiant energy is the energy of electromagnetic waves. It includes visible light, radio waves, and X-rays. Example: Sunlight is a form of radiant energy.

Front

What is Potential Energy?

Back

Potential energy is the stored energy in an object due to its position or state. Example: A rock at the top of a hill has potential energy.

Front

What is Kinetic Energy?

Back

Kinetic energy is the energy of an object in motion. The faster an object moves, the more kinetic energy it has. Example: A rolling ball has kinetic energy.

Front

How does energy transform from one type to another?

Back

Energy can change from one form to another. For example, when you eat food (chemical energy), your body converts it into kinetic energy when you run.

Front

What is an example of energy conversion in a light bulb?

Back

In a light bulb, electrical energy is converted into radiant energy (light) and thermal energy (heat).

Front

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.
