What is Albert Einstein's name for gravity? (called the General Theory of ___________)
Relativity
How many moons does Mars have?
Double Points for the name(s)
2
Phobos and Deimos
What is the name of the largest sun (or star) that we have found in our galaxy?
UY Scuti
bonus
List the planets in order by gravitational pull (Largest to smallest)
Jupiter, Saturn, Neptune, Uranus, Earth, Venus, Mars, Mercury
Which of these is the best way to describe our solar system?
a) It is a group of stars revolving around a single object
b) It is a single star revolving around a group of objects
c) It is a group of objects revolving around a single star
C
What unit do we use to measure DISTANCE in space for VERY FAR objects away from us?
Light Years (the distance a light beam travels in one years time)
Distance = 5,880,000,000,000 miles
bonus
Two factors effecting the magnitude (size) of the force of gravity between 2 objects are...
Mass and Distance
List 3 things that ALL the planets have in common
1) All spherical
2) All orbit the Sun
3) All have gravitational fields
Describe how the distances between the orbits of the inner planets (1st four from the sun) compare to the distances between the orbits of the outer planets (four farthest from the sun).
Inner planets - all spread out evenly and relatively close to each other
Outer planets - arranged randomly, spread out MUCH farther than the inner planets
bonus
What keeps the planets in a circular orbit around the sun
a) mass and distance
b) inertia and gravity
c) eccentricity and velocity
d) force and speed
B
Gravity pulls it straight down, but the planets also want to keep going straight due to inertia (Newton's first law). The middle point between those 2 forces causes a circular path around the sun.
Group the following planets by INNER and OUTER planets:
Mercury, Jupiter, Mars, Saturn, Uranus, Earth
INNER - Mercury, Earth, Mars
OUTER - Jupiter, Saturn, Uranus
How do the sizes of the inner planets (4 closest to the sun) compare to the sizes of the outer planets (4 farthest from the sun)?
Inner planets - Small
Outer planets - LARGE
If Earth's mass was cut in half, what would happen to your weight? BE SPECIFIC and Explain your reasoning
It would also be cut in half. Half Mass = Half Gravity = Half your weight
