Kepler's First Law states
objects attract other objects with a force that is directly proportional to the product of their masses
the square of the ratio of the periods of any two planets revolving around the Sun is equal to the cube of the ratio of their average distance from the Sun
An imaginary line joining a planet and the sun sweeps out an equal area of space in equal amounts of time.
Planets move about the Sun in an elliptical orbit with the Sun at one of the foci.

According to Einstein's Theory of Relativity, which of the most accurately describes time?
Time is a human construct and is constant
Time is a human construct and varies depending upon where an object is in space
Time is relative and varies depending upon how fast an object are traveling
Time is relative and varies depending upon how fast an object is traveling; the faster an object is traveling the slower time passes
When looking at the Earth's orbit, what can be said about summer and winter in the Northern hemisphere?
Because of its orbit, Earth is the same distance from the Sun in both the Northern hemisphere's summer and winter seasons.
Because of its orbit, Earth is further away from the Sun in the Northern hemisphere's winter season and closer during the summer season.
Because of its orbit, Earth is further away from the Sun in the Northern hemisphere's summer season and closer during the winter season.
None of the above accurately describe the Earth's orbit.
As an object moves further from the surface of the Earth, what happens to its mass?
The mass of the object will not vary as it moves further from the surface of the Earth
The mass of the object will decrease as it moves further from the surface of the Earth.
The mass of the object will increase as it moves further from the surface of the Earth.
Which of the following most accurately describes the movement of the Earth around the Sun?
The Earth moves at a constant speed around the Sun.
The Earth moves faster when it is closest to the Sun.
The Earth moves slowest when it is closest to the Sun.
The Earth's speed varies dependent upon the phase of the moon.
According to Einstein, what is a fourth dimension with which astronomers should be concerned when studying space?
Time
Space
Spacetime
Infinity
What would happen to the gravitational force if one of the masses is doubled and the radius is doubled?
The gravitational force would be quadruple the original.
The gravitational force would be double the original.
The gravitational force would be one-half the original.
The gravitational force would be one-fourth the original.
When in orbit around the Earth, what is true about the relationship between a satellite's distance from the Earth's surface and its velocity in order for the satellite to stay in its orbit?
A satellite's distance and velocity are inversely proportional; that is, the satellite must travel more quickly to stay in orbit.
A satellite's distance and velocity are directly proportional; that is, the satellite must travel less quickly to stay in orbit.
A satellite's velocity is not affect by its distance from the Earth's surface.
The distance from the Earth's surface is only dependent upon the mass of the satellite.
Which of the following is the most accurate description of "escape velocity"?
Escape velocity is the velocity needed to get away from the Earth's gravitational force.
Escape velocity is the velocity needed to get away from the Earth's gravitational force and is dependent upon the mass of the satellite.
Escape velocity is the velocity needed to get away from the Earth's gravitational force and not dependent upon the mass of the satellite.
Escape velocity is the velocity needed to get away from the Earth's gravitational force and not dependent upon the mass of the satellite but is dependent upon the geometric structure of the launch vehicle.
