Types of Energy - LVL 2

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. It is emitted by sources such as the sun and light bulbs.

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, and it increases as the temperature rises.

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, such as refrigerators and light bulbs.

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, and is calculated using the formula KE = 1/2 mv².

Front

What is elastic potential energy?

Back

Elastic potential energy is the energy stored in elastic materials as the result of their stretching or compressing. It is present in objects like springs and rubber bands.

Front

What is gravitational potential energy?

Back

Gravitational potential energy is the energy an object possesses due to its position in a gravitational field. It is calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It travels through air, water, and solids and is perceived by our ears.

Front

What is nuclear energy?

Back

Nuclear energy is the energy released during nuclear reactions, such as fission or fusion. It is used in nuclear power plants to generate electricity.

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 radiant energy?

Back

Radiant energy is the energy of electromagnetic waves, including light. It is the energy that travels through space and can be absorbed by objects.
