Question 1 (2 points)
A student researches Jupiter and Saturn and records the following information:
1. Jupiter is about half the distance to the Sun compared to Saturn.
2. Jupiter is about three times more massive than Saturn.
Based on this information, which of the following can be concluded about the gravitational force between the planets and the sun?
Question 1 options:
There are no gravitational forces between Jupiter and the sun or between Saturn and the sun.
There is a greater gravitational force between Jupiter and the sun than between Saturn and the sun.
There are equal gravitational forces between Saturn and the sun and between Jupiter and the sun.
-------------------------------------------------------------------------------------------
There is a greater gravitational force between Saturn and the sun than between Jupiter and the sun.
Question 2 (2 points)
The movement of the planets and other celestial bodies in the Solar System is caused by
Question 2 options:
waves of solar radiation moving away from the Sun.
the repulsion of neighboring planets in the Solar System.
the sun's gravitational force
-------------------------------------------------------------------------------------------------------------
the pull from the edges of the Solar System.
Question 3 (2 points)
The image above was taken by the Galileo spacecraft as it visited the asteroid belt on its way to Jupiter. Shown in the image are two rocky-iron bodies. The large object on the left is an asteroid named Ida. The object on the right, which measures only about 1 mile across, is named Dactyl.
Dactyl is a tiny moon that orbits the asteroid Ida. Dactyl orbits Ida due to
Question 3 options:
the magnetic force field that defines the asteroid belt.
electrical energy transferred between the two objects
small differences in the objects' rocky-iron compositions.
------------------------------------------------------------------------------------------
the mutual gravitational attraction between the two objects.
Question 4 (2 points)
Make the selection that best completes BOTH blanks.
The farther a planet is from the sun, the _________ its orbital motion is, and the _________ the gravitational attraction between the planet and the sun is.
Question 4 options:
slower, stronger
slower, weaker
faster, weaker
----------------------------------------------------------------------------------------------
faster, stronger
Question 5 (2 points)
What prevents the Sun's gravitational attraction from pulling the Earth out of its orbit and into the Sun?
Question 5 options:
gravitational attraction
magnetic attraction
electrical attraction
inertia
