Because the stars in the constellations are so far away
Because the stars in the constellations move so slowly- typically about the speed of a snail- that their motions are not noticeable
Because the stars in the constellations are not moving
Because the stars in the constellations all move at the same speeds and in the same directions, so they don't change their relative positions
The seasons would be less extreme, because the Sun's rays would be less direct in the summer, and more direct in the winter
The seasons would be less extreme, because the surface of the Earth would be farther from the Sun in the summer, and closer to the Sun in the winter
The seasons would be more extreme, because the Sun's rays would be more direct in summer, and less direct in winter
The seasons would be more extreme, because the surface of the Earth would be closer to the Sun in the summer, and farther from the Sun in the winter
Less than the thickness of a human hair held at arm's length
Slightly more than a width of a basketball held at arm's length
About the width of a finger held at arm's length
About the width of your fist held at arm's length
Stars were too far away for parallax to be measured with available technology
Earth is stationary at the center of the universe
Galileo's theories of the universe were essentially correct
Stars must all lie at the same distance from Earth, on the celestial sphere
The answer depends on whether it's winter or summer
30 degrees up, due West
On the northern horizon
The answer depends on what time of day (or night) it is
Directly overhead
The planet moves backward through the sky
The planet moves backward in its orbit around the Sun
The planet moves through constellations that are not part of the zodiac
The planet rises in the west and sets in the east
The planet appears to move eastward with respect to the stars over a period of many nights
It does not have seasons
It uses a 23-hour rather than a 24-hour day
It has about 11 fewer days
Its new year always occurs in February instead of on January 1
The Milky Way is composed of many individual stars
Patterns of shadow and sunlight near the dividing line between the light and dark portions of the Moon's face
Four moons of Jupiter
Phases of Venus
The period of a planet does not depend on its mass
A planet's period does not depend on the eccentricity of its orbit
All orbits with the same semi-major axis have the same period
Planets that are farther from the Sun move at slower average speeds than nearer planets
All of the above are correct
Semi-major axis
Perihelion
Eccentricity
Aphelion
Period
A circle is considered to be a special type of ellipse
The focus of an ellipse is always located precisely at the center of the ellipse
The semi-major axis of an ellipse is half the length of the longest line that you can draw across an ellipse
An ellipse with a large eccentricity looks much more elongated (stretched out) than an ellipse with a small eccentricity
Because the gravity from the Moon cancels out the gravity from Earth
Because there is no gravity in space
Because they are falling around the Earth
Because they are moving so fast
Decreases, because the force of gravity strengthens as the cloud shrinks
Increases, because the force of gravity strengthens as the cloud shrinks
Decreases, because its angular momentum is conserved
Increases, because its angular momentum is conserved
Increases, because its total energy is conserved
Direction
Speed
Momentum
Mass
The energy goes into the ground, and as a result, the orbit of the Earth about the Sun is slightly changed
It is transformed back into gravitational potential energy
The rock keeps the energy inside it in the form of mass-energy
The energy goes to producing sound and to heating the ground, rock, and surrounding air
Actually only three of seven distinct laws of planetary motion
Natural consequences of the law of universal gravitation
The key to proving that Earth orbits our Sun

You can make mass into energy if you can accelerate the mass to the speed of light
It takes a large amount of mass to produce a small amount of energy
A small amount of mass can be turned into a large amount of energy
One kilogram of mass represents 1 joule of energy
Mass can be turned into energy, but energy cannot be turned back into mass
Inversely proportional to the distance between objects
Directly proportional to the distance between objects
Not dependent on the distance between objects
Directly proportional to the square of the distance between objects
Inversely proportional to the square of the distance between objects

Not change at all
Increase by a factor of 4
Measuring the orbital period and distance of Jupiter's orbit around the Sun
Knowing the Sun's mass and measuring the average distance of Jupiter from the Sun
Measuring the orbital speed of one of Jupiter's moons
Knowing the Sun's mass and measuring how Jupiter's speed changes during its elliptical orbit around the Sun
Measuring the orbital period and distance of one of Jupiter's moons
The 10-pound weight will hit the ground before the 5-pound weight
Both weights will float freely, since everything is weightless on the Moon
Both will hit the ground at the same time
The 5-pound weight will hit the ground before the 10-pound weight
Infrared light has higher energy, and moves faster
Infrared light has higher energy, but the same speed
Visible light has higher energy, and moves faster
Visible light has higher energy, but the same speed
You will see two distinct stars in your photograph
The photo will seem to show only one star rather than two
The two stars will appear to be touching, looking rather like a small dumbbell
The stars will not show up at all in your photograph
