Kepler's 1st Law
Is an ellipse the same thing as a circle?
No.
What is the relatonship between A1, A2, and A3?
A1=A2=A3
What is T and R in the equation T² ∝ r³
T is "time", and r is "average radius"
Who made this law?
Newton duh
Who did Kepler get his work from?
Brahe.
What do you call the two points on an ellipse?
They're called "Foci".
What is the point called when the Earth it the farthest to the sun?
Aphelion.
Do the outer planets travel faster or slower than the planets closer to the Sun?
The planets travel slower than the planets closer to the sun.
What is the relationship between F1 and F2
The force between objects. So F1 is equal to F2.
Which planet has the longest orbital period? (In Earth Years)
Pluto.
What is Kepler's 1st Law of Planetary Motion? (How'd you state it?)
The orbit of each plane around the sun is an ellipse (not a circle) with the sun at one focus.
What is the point called where a planet reaches it's fastest speed(Closest point to the sun/focus)
It moves the fastest at it's perihelion.
What is the equation that explains this law?
T² ∝ r³
What is the relationship between mass and force of gravity?
When the mass of an object increases, the force of gravity increases.
What is the third planet from the sun?
Earth.
Does the eccentricity affect the shape of the ellipse?
Yes it does, it causes it to become more flat.
What is Kepler's 2nd Law of Planetary Motion? (How'd you state it?)
"The imaginary line joining a planet and the sun sweeps equal areas (a) of space during equal time intervals (t) as the planet orbits."
What is Kepler's 3rd Law of Planetary Motion? (How'd you state it?)
"The time it takes for a planet to orbit the sun is proportional to it's average distance from the sun"
What is Newton's Graviational Force?
"All objects in the universe pull on each other with a force determined by the mass of the objects and their distance apart"
What's the name of the college on the sticker on the back of Mrs Matzo's computer?
It is University of Michigan.
If you were to rank the planets and sort them from least eccentric, to most eccentric, which planet would be right in the middle?
Mars.
What is true to the imaginary areas to it's time?
They're equal.
What's the relationship between orbital speed and the average distance from the sun (In Astronomical Units)
The greater the orbital speed, the closer it's average distance to the sun.
What is the equation for Newton's Gravitational Force?
Fg = (G * M1 * M2) / d^2
What is the acceleration of gravity?
9.8 m/s²
