Vocabulary
A push or a pull that acts on an object
Force
If a sound source vibrates slower, what happens to the pitch?
The pitch becomes lower.
Increasing the amplitude of a vibration makes the sound...
Louder
What is the Pacific Ocean?
What is Mars?
Moving back and forth, or side to side, or up and down repeatedly, past its starting point
vibrate
What does a low frequency sound graph look like?
less peaks and valleys
big wavelength
What does a sound source do to the particles around it?
t causes the nearby particles to vibrate, initiating the particle-to-particle collision through the medium that makes sound travel.
This desert is the largest in the world.
What is Antarctica?
The process plants use to turn sunlight into energy is called this.
What is photosynthesis?
Distance from the starting position to a peak or a valley
Amplitude
What determines a sounds pitch?
frequency (length of bars/strings)
Why does a vibrating object continue to vibrate even after you stop pushing on it?
The object will vibrate and deform past its starting point until their is no energy left
This country has the most population in the world as of 2024
What is India?
This is the hardest natural substance on Earth.
What is diamond
The highness or lowness of a sound.
Pitch
On a motion graph of a vibrating object, how can you tell which sound is higher pitched?
Amount of peaks and valleys (frequency) and smaller wavelength
What happens to a sound source’s vibrations when the sound has a higher pitch
The sound source vibrates faster, or with a higher frequency
This river is the longest in the United States
What is the Missouri river?
This part of the cell controls the cell’s activities and contains DNA.
What is the nucleus
What does sound need to travel through?
Two sounds have the same amplitude but different frequencies. How will they sound different?
One could be a high, medium or low pitch at the same amplitude.
Why can sound make another object move (like the window in the anchoring phenomenon)?
The sound source’s vibrations transfer energy through particle collisions in the medium, causing the sound receiver to vibrate and deform past its starting point.
This is the capital of Brazil
What is Brasilia?
This force keeps planets in orbit around the Sun.
What is gravity?
