What is Kinetic Energy?

Energy a particle or object has due to motion.

100
Give an example and define the doppler effect.
Apparent change in frequency of a sound caused by the motion of the source or the listener.
100
An echo will most likely occur on a surface that is???
Smooth and hard
100
How can you protect your hearing?
use earplugs
200
The part of the ear that collects sound waves
Outer Ear
200

What is Potential Energy?

The potential an object has to gain or be set in motion. 

200

How can a speaker play multiple different sounds?

It generates many different sound waves with varying pitch and frequency. 

200
The amplitude of a sound's waves affect?
Loudness
200

Example of someone who may suffer hearing loss in their career

Rock Star, Mr. Fritz, etc..

300
Sound is created by?
The vibration of particles through a medium.
300

When two objects collide, thier forces are?

Equal and Opposite

300
What unit is used to express loudness?
Decibel (dB)
300
What does the frequency of a sound wave affect?
Pitch
300
What is needed for sound to travel?
Medium
400
A substance a wave can travel through is?
A Medium!
400

How does a state of matter change?

Energy either leaves or enters the system.

400
What are two factors that influence the speed of sound?
Material of the medium and temperature. (solid, warm)
400

If a wave occurs 3,200 times every 8 seconds, what is its frequency?

400 Hertz

400
Why won't sounds travel in a vacuum?
No particles to vibrate
500
Sounds travels fastest through what type of medium?
Solid
500

What is the equation to Kinetic Energy?

K= 1/2mv^2

500
Define Pitch
How high or low a sounds seems
500

If we track one particle in a wave, why does it not travel down the entire medium?

Waves transfer energy not matter.

When will you hear a sonic boom?
When a shock wave reaches your ears
