Energy types and transformations

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.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor. It is commonly used to power devices and appliances.

Front

What is light energy?

Back

Light energy is a form of electromagnetic radiation that is visible to the human eye. It is produced by sources like the sun, light bulbs, and fire.

Front

What is potential energy?

Back

Potential energy is the stored energy in an object due to its position or state. It has the potential to be converted into kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion. It depends on the mass of the object and its velocity.

Front

What is energy transformation?

Back

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

Front

Example of energy transformation from chemical to electrical energy?

Back

A battery converting chemical energy into electrical energy when it powers a device.

Front

Example of energy transformation from electrical to thermal energy?

Back

A toaster converting electrical energy into thermal energy to toast bread.

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.

Front

What happens to energy in a closed system?

Back

In a closed system, the total energy remains constant; energy can change forms but the total amount does not change.
