Which theory does this diagram illustrate?
Aristotle's Theory
Geocentric Theory
Heliocentric Theory
Ptolemy's theory
2
Which statement is
not
part of Copernicus' theory of the Solar System?
Planets orbit the sun in elliptical orbits.
Earth rotates on its axis, causing day and night.
The sun remains stationary.
Earth revolves around the sun, causing seasons.

4
What did Lee's calculation's demonstrate?
Kepler's 1st Law
Kepler's 2nd Law
Kepler's 3rd Law
Newton's Law of Universal Gravitation
5
How does Aristarchus' view of the Solar System compare with Aristotle's view?
Their theories do not differ, because both are heliocentric.
Aristarchus' is heliocentric, Aristotle's is geocentric.
Their theories do not differ, because both are geocentric.
Aristarchus' is geocentric, Aristotle's is heliocentric.
6
Which term
best
describes the shape of the orbits of planets in our solar system?
centripetal
spherical
elliptical
circular
7
What did Galileo's observations of Jupiter's moons show?
All celestial bodies orbited Earth.
All celestial bodies orbited the sun.
Planets had elliptical orbits.
Planets other than Earth had bodies moving around them.
8
What is gravity?
rotating cloud of gas and dust from which solar system forms
point in the orbit at which planet is furthest from the sun
a force of attraction between objects due to their masses
unbalanced force that makes objects move in elliptical path
9
Who developed this model to support Aristotle's theory of the universe?
Copernicus
Aristarchus
Galileo
Ptolemy
10
What role did gravity play in the formation of the sun?
Caused small particles to collide to form planetesimals
Caused protoplanetary disk to rotate and form solar nebula
Caused protoplanetary disk to rotate and become planetesimal
Caused solar nebula to collapse toward center
11
According to Kepler's laws, how do planets move in the Solar System?
circular orbits around Earth
elliptical orbits around Earth
circular orbits around the sun
elliptical orbits around the sun
12
What did Galileo conclude from his observations of Venus?
It is farther from the sun than Earth is.
It has moons and the moons have phases.
It travels around the sun.
It is always lit.
13
How did Aristotle explain the way that objects in the Universe move?
elliptical orbits on one giant sphere with Sun at the center
circles on small spheres in large spheres w/Earth at center
elliptical orbits in spheres with Earth at the center
circles on one giant sphere with Earth at the center
14
Which term describes a small body from which a planet forms?
orbit
planetesimal
protoplanetary disk
solar nebula
15
Which description would be used to explain the solar nebula?
small body from which a planet originates
rotation cloud of dust and gas
rocky core surrounded by a deep atmosphere of gas and ice
disk of material surrounding a young star
16
Which term describes a force of attraction between two objects that results from their masses?
planetesimal
gravity
orbit
aphelion
17
Which of these choices states Newton's law of Universal gravitation?
As a planet orbits, it covers equal areas in equal time.
Gravity increases as mass increases or distance decreases.
The orbit of the planet is an ellipse w/sun at one focus.
p2 = a3
18
The distance between Mercury and the sun is 0.387 AU. What is the orbital period of Mercury?
0.0598 Earth years
0.2407 Earth years
0.5311 Earth years
1.0775 Earth years
19
How did Aristotle explain that no parallax was observed when viewing the stars?
Viewers need to move to observe parallax.
The stars are very far away.
Earth is not moving.
Parallax is undetectable to the eye.
20
How does Ptolemy's model of the universe compare with Aristotle's model?
Both models show celestial objects have elliptical paths.
Both models show celestial objects have circular paths.
Both models are based on parallax.
Both models are heliocentric.
