RG037003

As sound moves through air, molecules that make up air vibrate and collide with each other. As the molecules collide, energy is transferred from one molecule to the next.

RG038003

The distance between the molecules that make up the matter and how far they are displaced by the sound affect how much energy can be transferred by sound.

RG039003

Sound transfers energy through matter as the molecules that make up the matter collide with one another.

RG193001

As sound travels through water, matter is displaced for a period of time but then returns to its original position after the sound passes.

RG194001

As sound from a speaker travels through water, the matter moves back and forth in a wavelike motion.

RG195001

Sound transfers energy from a sender to an object by a series of molecular collisions, but the molecules do not travel from the sender to the object.

RG024003

Any sound made by a guitar can cause the air in a room to vibrate, and these vibrations transfer energy from the guitar to a person's ear.

RG027004

Even though a person’s ear won’t feel any different while listening to music, sound does transfer a small amount of energy to the person’s ear, which makes parts of the ear vibrate.

RG028004

After a drummer hits a drum once, the energy of the drum will decrease because the sound will transfer energy away from the drum.

RG040003

When a tuning fork slows down and eventually stops vibrating, some of the energy is transferred to the surrounding air.

RG069003

Energy is transferred from a person to a triangle as the person hits it, and then energy is transferred away from the triangle by sound after the person stops hitting it.

RG026004

As sound travels through a liquid, the matter is displaced for a period of time but then returns to its original position after the sound passes.
