Momentum
What is the unit for momentum
kg*m/s
A word meaning "center seeking"
Centripetal
Do waves move matter?
No, they move energy
What is the variable for speed of light
c
What should I major in?
Something that you are able to motivate yourself to do even when you don't want to do it
The equation for momentum
Equation for centripetal acceleration
ac = vt2/r
This wave displaces matter in the same direction it travels.
Longitudinal/Pressure wave
What is the speed of sound at 0 degrees celcius
331m/s
Should I go to my professor's office hours?
Yes
How are velocity and momentum related
Directly proportional (one goes up the other goes up)
What changes as you change distance from the center in circular motion
tangential speed
The equation for wave speed
v= (wavelength)*(frequency)
Can sound travel through space?
No, in space no one can hear you scream (the second part or knowledge of the movie it is from is necessary for points)
Should I leave my clothes in the washing machine all day preventing other people from using them?
No
Who has more momentum, a 400N person moving 5m/s or a 600N person moving at 3m/s
The 400N person
What is the centripetal force of a 1kg ball being swung on a 5m rope with a speed of 5m/s?
5N
Find the wavelength of a wave with a frequency of 5hz and a speed of 10m/s
2m
What never changes about light as it goes through different mediums
It's wavelength
What is the most important quality in a roommate?
That they don't mess with you sleep schedule
Explain why football pads and baseball gloves work?
They increase contact time, which causes less force to be applied for the same change in momentum.
What is the fake force and why is it fake?
Centrifugal force. It is fake because it is a product of inertia not seen in all frames of reference
What is the difference between mechanical and electromagnetic waves
Electromagnetic waves can travel through a vacuum
Explain why counting until you hear thunder after seeing a lightning strike works to tell how far away a storm is
Light is faster than sound so the difference in time they take to reach you can be used to show how far away a storm is.
Should I eat a balanced diet when I'm at college?
Yes, scurvy is not fun you aren't a pirate (I hope)
