VERSION!!
You observe a full moon rising at sunset. What will you see 6 hours later?
a full moon on or near your meridian
When we see Venus in its new phase, what phase would Earth be in as seen
by a hypothetical Venetian?
full
Which of the following statements about the orbits of the planets is true?
The eight major planets go around the Sun in the same direction and do so
all in the same plane like a disk.
According to Kepler's third law (p2 = a3), how does a planet's mass affect
its orbit around the Sun?
A planet's mass has no effect on its orbit around the Sun.
Suppose the Sun were to shrink suddenly in size while its mass stayed the
same. According to the law of conservation of angular momentum, what
would happen?
The Sun's rate of rotation would speed up.
,Imagine a Star Wars type spaceship in orbit around a planet. Its engine
suffers a severe malfunction, and explodes. What is the most physically
realistic depiction of this event?
The spacecraft breaks apart, and the pieces continue to orbit the planet.
Conservation of angular momentum dictates that the orbital speed of a planet
is faster when it is closer to the Sun and slower when it is farther away.
How would the gravitational force between Earth and Moon change if the
Moon were moved 4 times further away?
The force would be 16 times weaker.
Which planet is moving more slowly around the Sun?
Jupiter
Why are astronauts weightless in the Space Station?
because the Space Station is free falling around the Earth.
The mass of Jupiter can be calculated by measuring...
...the orbital period of one of Jupiter's moons and the distance between
Jupiter and that moon.
, The surface gravity on the Moon is about 1/6 that of Earth. What is the mass
of a 72 kg person on the Moon?
72 kg
The acceleration due to gravity near the surface of the Earth is about 10
m/s2. How fast is a rock falling if it has been falling for 3 seconds?
30 m/s
Light travels at 300,000 km/sec. About how far does light travel in 10 years?
About 10 light-years
"Roses are red, violets are blue ... ". But why is this?
Roses reflect more red light than other wavelengths, violets reflect more
blue light than other wavelengths
From lowest energy to highest energy, which of the following correctly
orders the different categories of electromagnetic radiation?
radio, infrared, visible light, ultraviolet, X rays, gamma rays
One star is emitting primarily visible light and another star is emitting
primarily infrared light. Which star is hotter?
The star emitting visible light.
