What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons. It is used to power devices like lights, radios, and computers.

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. It is released during a chemical reaction.

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.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves. It is a form of mechanical energy that travels through air, water, or solids.

Front

What is the transformation of energy?

Back

Energy transformation is the process of changing energy from one form to another, such as electrical energy transforming into light energy in a light bulb.

Front

What happens when electrical energy is transformed into thermal energy?

Back

When electrical energy is transformed into thermal energy, it produces heat. This is how devices like toasters and heaters work.

Front

What is an example of energy transformation in a lamp?

Back

In a lamp, electrical energy is transformed into light energy and thermal energy when it is turned on.

Front

What is the energy transformation when a battery powers a toy?

Back

The energy transformation is chemical energy from the battery being converted into mechanical energy to move the toy.
