Unit 2 Lesson 2 Sound and Light

Front

What is sound?

Back

Sound is a form of energy that travels in waves and can be heard when it reaches our ears.

Front

Can sound travel through outer space?

Back

No, sound cannot travel through outer space because there is no medium (like air or water) for it to travel through.

Front

What is light?

Back

Light is a form of energy that allows us to see objects.

Front

How does sound energy travel?

Back

Sound energy travels in waves.

Front

What is kinetic energy?

Back

Kinetic energy is the energy of motion.

Front

What is potential energy?

Back

Potential energy is stored energy that has the potential to do work.

Front

What happens when you transform stored energy to energy of motion?

Back

It means that the stored energy is converted into kinetic energy, allowing an object to move.

Front

What is the fastest medium for sound to travel through?

Back

Sound travels fastest through solids.

Front

What is an example of a device that transforms energy?

Back

A pom-pom launcher transforms stored energy to energy of motion.

Front

What are sound waves?

Back

Sound waves are vibrations that travel through a medium, such as air, water, or solids.
