Sound Basics
What makes sound?
Vibrations
High-pitched sounds have long or short wavelengths?
Short
Energy is the ability to cause __________.
Motion
What pattern helps predict roller coaster speed?
Taller first hill = faster speed
What happens when two objects collide?
Energy transfers
Sound is a type of __________ wave.
Mechanical wave
Low-pitched sounds have long or short wavelengths?
Long
Objects moving faster have more or less energy?
More
Who went fastest in the sled races: the highest starter or lowest?
Highest starter
Does all energy transfer during a collision?
No
What does sound travel through: air, space, or water?
Air
Which animal has a longer wavelength: a bird or a whale?
Whale
A roller coaster with a taller first hill will go faster or slower?
Faster
Why did Mateo always beat Katy in the races?
Mateo started higher and had more energy
What two things can energy transfer cause during a collision?
Sound and movement
What happens to the air near a speaker when sound is made?
The air vibrates
True or False: Pitch is determined by how tall the waves are.
False
Why does a taller hill give an object more energy?
Because it starts with more energy
What should Robb change to win the next race?
Start higher on the hill
When a black bowling ball hits a gray one, what happens?
Some energy transfers and the gray ball moves
How can sound cause a window to move or break?
Sound waves vibrate the air, which makes the window vibrate
How would a high-pitched sound look when modeled with a string?
Waves close together (short wavelength)
Use energy to explain why a roller coaster speeds up going downhill.
Energy increases speed as it moves
Explain how height, energy, and speed are connected.
Higher start gives more energy, which causes faster speed
Why would fewer pins fall after the bowling balls collide first?
The gray ball has less energy
