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.

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.

RG190001

Energy is transferred when warmer air moves from one place to another and when a person listens to music on a radio.

RG025004

How loud a sound is and how high or low its pitch is affects how much energy is transferred from a radio to a person listening to the radio

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.

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.

RG103002

There are a number of different ways the amount of energy something has can change, for example, by changing its motion or heating it.

RG104002

There are a number of different ways the amount of energy a tree has can change, for example, when the tree grows or when the sun warms it.

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.

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.
