Front

What is energy transfer?

Back

Energy transfer is the process of energy moving from one object or system to another.

Front

What are the forms of energy?

Back

The main forms of energy include heat energy, light energy, sound energy, and kinetic energy.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion. An object in motion has kinetic energy.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work, such as a marble at the top of a ramp.

Front

What happens to energy when a book falls off a shelf?

Back

The book transforms potential energy into kinetic energy as it falls.

Front

What is heat energy?

Back

Heat energy is the energy that comes from the temperature of matter. It is transferred from hot objects to cold objects.

Front

Can energy be created or destroyed?

Back

No, energy cannot be created or destroyed; it can only be transformed from one form to another.

Front

What is an example of energy transformation?

Back

When a light bulb is turned on, electrical energy is transformed into light energy and heat energy.

Front

What is the role of a power plant?

Back

A power plant transforms energy from natural resources (like coal or sunlight) into electrical energy.

Front

What is sound energy?

Back

Sound energy is the energy produced by vibrating sound waves.
