How high are you jumping at twice Earth's mass compared to Earth's mass? - ✔✔Half as high
Since the jump height is half as high what does that tell us about gravity? - ✔✔Twice as much. (More
gravity = lower jump height)
Now we can change the mass to 0.5M. If we do, how much higher are you jumping than at one Earth
mass? - ✔✔Twice as high
Now we can change the mass to 0.25M. If we do, how much higher are you jumping? - ✔✔Four times as
high
As the mass of the planet increases, the jump height _______ by the same factor as the mass. -
✔✔Decreases
Let's keep the mass at Earth's mass but change the radius to half the radius of the earth. How much
higher do you jump? - ✔✔One-quarter as high
Let's keep the mass at Earth's mass but change the radius to twice the radius of earth. How high do you
jump? - ✔✔Four times as high
Let's keep the mass at Earth's mass but change the radius to three times the radius of the earth. How
high do you jump? - ✔✔Nine times as high
As the radius of the planet increases, the jump height _____ as the square of the radius. - ✔✔Increases
What is the relationship between gravity, mass and radius? - ✔✔g ∝ m/r^2
,Experiment using Mars' and Earth's gravity to see what effect they have on gravity. What is its surface
gravity compared to Earth? (Mars has about 1/10 the mass and 1/2 the radius of Earth) - ✔✔0.4 times
The Moon has about 1/100 the mass of Earth and about 1/4 the radius. What is the surface gravity of
the Moon compared to earth? - ✔✔16/100
Jupiter has about 300 times the mass of Earth and 10 times the radius. What is the surface gravity of
Jupiter compared to Earth? - ✔✔3
Saturn has about 100 times the mass of Earth and 10 times the radius. What is the surface gravity of
Saturn compared to Earth? - ✔✔1
Notice that the moon in the panel at the upper right is half illuminated. Now, how much of the TOTAL
surface of the Moon is illuminated in this phase? - ✔✔50%
Now, how much of the TOTAL surface of the moon is illuminated in the Full Moon phase? - ✔✔50%
(moon is always illuminated 50%)
What time is it for any observer on Earth when they see the full Moon rising? - ✔✔6PM (Full Moon rises
at sunset)
Sunset occurs 6 hours before the Full Moon transits. Now, when does the Full Moon set? - ✔✔6AM (Full
Moon sets at sunrise)
When does the Waxing crescent phase (overhead for the green observer in the picture) RISE? Keep in
mind that the Earth is rotating counter clockwise. - ✔✔9AM
When does the Waning Gibbous phase SET? - ✔✔9AM
What phase must the moon be in so that an observer on Earth will see the Moon overhead at 9AM? -
✔✔Waning Cresent
, Where on the sky does the Moon set? - ✔✔West
Both the Moon and the Sun rise and set for the same reason. It is because of: - ✔✔the rotation of the
Earth
Sun is eclipsed when the Moon is New. That is the only way that is could block the Sun's light. Is it
daytime or nighttime when this occurs? - ✔✔Day
What phase is the Moon in during a lunar eclipse? - ✔✔Full
Is is daytime or nighttime when [the lunar eclipse] occurs? - ✔✔Night
We don't see a solar eclipse from Earth every single month. Oh, I see, the reason is that: - ✔✔the
Moon's orbit around Earth is actually tipped about 5 degrees to Earth's orbit around the Sun so the
Moon isn't always in the right plane for an eclipse to occur
The inclination [of Phobos] is: - ✔✔About 1 degree
That means Phobos eclipses: - ✔✔every orbit
The orbital year [of Phobos] is: - ✔✔about 8 hours
If Earth's Moon was Full on May 1, 2007. When was it next in the First Quarter phase after this Full
Moon? - ✔✔May 22
How much of the total surface area of the Moon is illuminated by sunlight during the Full Moon phase? -
✔✔one half
At approximately what time does the third quarter Moon rise? - ✔✔midnight
