non-contact forces
100
The force between two objects rubbing together creating heat
What is friction?
100
The highest point of a transverse wave.
What is the crest?
100
What is the name of the force between to magnets?
magnetic force
100
T or F
Frequency and wavelength are inversely proportional; as one increases, the other must decrease.
True
100
The non-contact force that pulls everything on Earth towards its center.
What is gravity?
200
The law that states that objects in motion stay in motion and objects at rest stay at rest...or the law of inertia.
What is Newton's 1st law?
200
When a wave bounces off of a medium.
What is reflection?
200
The area around the magnet that shaped the iron filings in our lab
magnetic field
200
What is the first wave type in an Earthquake?
P waves or Primary waves
200
The non-contact force created by aligned flow of electrons. (hint: and has poles where opposites attract)
magnets
300
The law that is known as the "action-reaction" law. For every action there is an equal and opposite reaction.
What is Newton's 3rd law?
300
When a medium always some light through but "scatters" or changes its path. The medium is considered...
What is translucent?
300
These waves, often used for broadcasting, have the longest wavelengths and lowest frequencies in the spectrum.
Radio
300
Wave Refraction happens because air and water are different in what way?
Density
300
Electricity is the flow of what?
electrons
400
If a car is moving at 50mph on cruse control, you can describe the forces as .....
what is balanced?
400
When all the colors of the visible spectrum are absorbed, what color do we see?
what is black?
400
These high-energy waves are commonly used by doctors to image bones but carry more energy than visible light.
x-rays
400
Unlike electromagnetic waves, mechanical waves require this—a solid, liquid, or gas—to travel through.
Medium
400
This is the number of complete waves that pass a certain point in one second. It's what we measure wave length in.
Hertz
500
If a swimmer kicks off the wall with 50N of force to the right, the walls pushes on the swimmer with....
What is 50 N to the LEFT?
500
The distance between to crests?
what is wavelength?
500
This specific type of electromagnetic "radiation", which can cause sunburns, is largely blocked by the Earth's ozone layer. It is the first layer out of our visual spectrum. What type of radiation is it?
Ultra Violet Radiation
500
In this type of mechanical wave, the particles of the medium move perpendicular to the direction the wave is traveling.
Transverse
500
Name 3 ways to make this stronger.
More loops, closer loops, stronger batter, more magnetic core, bigger nail.
