The law that states that planets orbit in an elliptical orbit rather than a circle.
What is Kepler's First Law
100
Define each of the variables in the Law of Universal Gravitation equation.
F = force of gravity. G = gravity constant. m1 = mass of one object. m2 = mass of the second object. r = distance between the two objects.

Terrestrial planets that has a surface most like the moon
Mercury
100
The largest planet
Jupiter

List the planets in order from the sun
mercury venus earth mars jupiter saturn uranus neptune pluto
200
The law that states that an imaginary line between the sun and a planet sweeps out equal area in equal time
What is Kepler's Second Law
200
The equation for Newton's Law of Universal Gravitation
page 779. F = G * m * m / r^2
200
why mars has much bigger volcanoes than earth
There are no plate tectonics, so the volcanic vent remains in one place and the lava can build up
200
The planet with a moon that has a retrograde orbit
Neptune
200
Term that describes how we see a planet moving opposite around the sun when we are moving much faster past them.
What is retrograde motion
300
Draw Kepler's First Law. Include: sun, earth, perihelion, aphelion, foci and semimajor axis
bottom figures on page 776 and 777
300
The pair of objects that exert the most force on each other if the force between the earth and a student is 600 N and the force between two students is 3*10^-8 N. (earth&student or student&student)
The earth and the student have more force because the earth has a great mass
300
Why Venus does not have many impact craters.
Thick atmosphere burns up any objects that come close to Venus.
300
The planet with a magnetic field that is 1000x that of earths
Saturn
300
How Saturn’s rings were formed
a moon was destroyed either by saturn's gravity or by a collision and the debris formed rings
400
The equation for Kepler's 3rd law. Define each of the variables.
a^3 = P^2. a = semimajor axis (how far the planet is from the sun). P = orbital period (how long it takes for a planet to go around the sun once)
400
Describe how the force between two bodies depends on their masses and the distances between them
more mass = greater force. Closer = greater force
400
Standing on this planet would make you feel like you were under 1000m of water
Venus
400
The reason for the blue color of neptune and uranus
What is methane
400
Why Pluto is classified as a dwarf planet
It is part of the Kuiper asteroid belt
500
Mars is 1.5 AU from the sun. How long does it take for mars to orbit around the sun?
If one student has a mass of 80kg and is 8m away from another student that has a mass of 60 kg, what is the force of gravity between them? SHOW WORK WITH UNITS – SHOW THE FOUR STEPS
F = 5*10^-9
500
The two planets that do not have moons
mercury and venus

The length of one Jupiter day
10 hours

Difference between meteoroid, meteorite and meteor
meteoroid: object that enters earth's atmosphere and gets burned up. Meteorite: object that hits earth. Meteor: streak of light created when a meteoroid is being burned up.
