ASTRO 7N Unit 1 and 2 Game Questions
How high are you jumping at twice Earth's mass compared to Earth's mass? - correct
answer-Half as high
Since the jump height is half as high what does that tell us about gravity? - correct
answer-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? - correct answer-Twice as high
Now we can change the mass to 0.25M. If we do, how much higher are you jumping? -
correct answer-Four times as high

earth. How high do you jump? - correct answer-Nine times as high

correct answer-Increases
What is the relationship between gravity, mass and radius? - correct answer-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) - correct answer-0.4 times

gravity of the Moon compared to earth? - correct answer-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? - correct answer-3

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? - correct answer-50%

answer-6PM (Full Moon rises at sunset)
Sunset occurs 6 hours before the Full Moon transits. Now, when does the Full Moon set? -
correct answer-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. - correct answer-9AM
When does the Waning Gibbous phase SET? - correct answer-9AM
What phase must the moon be in so that an observer on Earth will see the Moon overhead
at 9AM? - correct answer-Waning Cresent
Where on the sky does the Moon set? - correct answer-West
Both the Moon and the Sun rise and set for the same reason. It is because of: - correct
answer-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? - correct answer-Day
What phase is the Moon in during a lunar eclipse? - correct answer-Full
Is is daytime or nighttime when [the lunar eclipse] occurs? - correct answer-Night
We don't see a solar eclipse from Earth every single month. Oh, I see, the reason is that: -
correct answer-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: - correct answer-About 1 degree
That means Phobos eclipses: - correct answer-every orbit
The orbital year [of Phobos] is: - correct answer-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? - correct answer-May 22
How much of the total surface area of the Moon is illuminated by sunlight during the Full
Moon phase? - correct answer-one half
At approximately what time does the third quarter Moon rise? - correct answer-midnight
, Approximately two weeks after a Solar Eclipse, what phase will the Moon be in? - correct
answer-Full
A moon orbits a planet in exactly the same plane as the planet orbits its star. How often does
this planet experience a solar eclipse? - correct answer-Once every orbit of its moon (its
month).
Summer Solstice: that's ______, right? - correct answer-June 21
Autumnal Equinox -- thats on or about _____, right? - correct answer-September 22
So, at the Winter Solstice, at noon, the sun is in (that is, appears in front of) which zodiac
constellation? - correct answer-Sagittarius
At midnight on March 21, we would be looking at _____, assuming the sky is clear! - correct
answer-Virgo
I guess because the asterisms we're most familiar with were - correct answer-drawn by
connecting the brightest, easiest-to-see stars as seen from Earth.
From Earth, in which constellations might you find the planet Saturn? - correct
answer-Taurus
Why don't we see the constellation Orion at night all throughout the year? - correct
answer-As the Earth orbits the Sun, its nighttime side points to different constellations at
different points along its orbit.
When is the best time for you to be able to see the constellation that is your sign of the
zodiac? - correct answer-At midnight six months after your birthday.
Constellations close to the North pole of Earth ______. - correct answer-Move in a circle
around the North star, Polaris, over the course of a single night.
There are a total of 88 constellations. Roughly how many of these can be seen at any given
time from a single location on a clear night? - correct answer-44
UV protection....that's 'UV' for _____, right? - correct answer-ultraviolet
And 'IR' for ______? - correct answer-infrared
Light is made up of little packets of energy called - correct answer-photons
A photon's _____ can be measure to determine its energy - correct answer-wavelength
Is light a particle or a wave? - correct answer-Both
Which one needed more energy to make -- long or short waves? - correct answer-SHORT
waves require more energy to generate
