How many laws did Kepler create in relation to planetary orbit?
Three

What are electromagnetic waves?
 They are a combination of electric and magnetic waves that ultimately characterize light.
100
Who discovered and wrote laws about gravity?
 Newton
100
The universe and everything in it is called ___________.
 Matter.
200
What is the formula from Newton's second law?
f=ma
200
Relative to a planet's elliptical orbit,  where is the  Sun located?
 One of the focal points.
200
 What is the wavelength? What about frequency?

Wavelength is the length between two crests of a wave.

Frequency is how many full cycles of a wave pass by a point in 1 second (measured in Hertz).

200
What two things is the strength of gravity dependent on?
The mass of the two objects and the distance between them.
200
 What qualities does matter have?
 It has mass and takes up space. 
300
Which of the laws is sometimes referred to as the "Law of Inertia"? What does it state?
The first law. An object at rest will remain at rest, an object in motion will remain in motion.

A line from the Sun to any planet sweeps out _______________ in _________________.

A line from the Sun to any planet sweeps out equal areas in equal times.

300
A high energy wave would have a ________ frequency and a ____________ wavelength. 
 High, short. 
300
What is its range?
Infinite.
300
 What is a force?
A push or pull experienced by matter. 
400
When we are walking or driving we push ourselves against the ground. What actually moves us forward? 
The ground's equal and opposite reaction pushing against us. 
400
What did Kepler determine that mathematically explains his findings?

The square of the orbital period (time it takes to complete one revolution around the Sun) is proportional to the cube of the orbit’s radius.

400
Which wave is the most penetrating? Which is the least?
Gamma, Radio
400
As the mass of objects increase, the strength of gravity between these objects will __________.
 Increase.
400
What are the four types of fundamental forces we learned about,  in order from strongest to weakest?
Strong nuclear, electromagnetic, weak nuclear, gravity. 
500
 If you have a block with an applied force of 350 N and a mass of 70 kg, how fast will the block accelerate?

5 m/s2

500
 How do Newton's laws help explain Kepler's laws?
Kepler's laws are a direct result of the gravitational attraction that is seen between any two objects, that Newton described in his own laws.
