Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus,Neptune
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Neptune,Uranus
Mercury, Venus, Earth, Mars, Saturn, Jupiter, Uranus,Neptune
18
Which of the following would cause gravity to become weaker?
a lot of mass
a decreased distance between 2 objects
an increased distance between 2 objects
nothing weakens gravity
19
If mass _______, the force of gravity increases. If distance ________, the force of gravity will increase.
increases, decreases
increases, increases
decreases, increases
decreases, decreases
20
A planet that is made of lighter elements which are gasses is a...
a moon.
terrestrial planet.
an asteroid.
a gas giant.
21
If the moon's gravitational pull is 1/6 of Earth's, what would a 60 pound child weigh on the moon?
10 lbs.
6 lbs.
36 lbs.
360 lbs.
22
Why is gravity acting on the outer planets of our solar system not as strong as the inner planets?
Gravity is the same on all planets in the solar system
The outer planets are bigger and have less gravity than smaller planets
The inner planets are smaller and have less gravity than the larger planets
The outer planets are further away and therefore gravity is weaker
23

a gas giant
a terrestrial planet
a moon
a comet
