Kepler's 1st law
The shape of all planets orbits
What is an ellipse?
The other name for Kepler's 2nd law is
What is the law of areas?
What is the law of areas?
The story behind newton discovering gravity
What is an apple falling near him / on his head?
All planets move at the fastest at this point (in their orbit)
What is Perihelion?
The part of the orbit the sun is located at
What is a focus?
The reason a planet moves faster when it is closer to the sun
The equation for Kepler's law is
What is T2 is proportional to r3?
The two variables behind gravitational attraction
What are distance and mass?
This term refers to a potential planet that has failed to fully clear its orbit from foreign bodies
What is a dwarf planet?
This makes an ellipse more eccentric
What is the focuses being further apart?
The reason planets do not move at a constant speed
Square the orbital period (in years) and distance (in au) and you get
What is one?
What force Isaac Newton discovered all objects have
What is a gravitational force?
The ancient Greek model of space (water earth, fire, what was space)
What is the aether?
This is what makes planets orbits eccentric (DAILY DOUBLE)
What is the imprecise process of planetary formation, and the nature of gravity?
What is the further apart the ellipses are?
Looking at this graphic, the value of R is *
fill in later
Gravity doubling would affect the solar system in this way
What is chaos with the orbits becoming faster?
This would occur (relating to the earths spread, ie the earth speeds up or slows down) if the earth was ejected from the solar system.
What is remain constant forever?
This graphic shows that the focuses are located at
What are C and D?
Based on the graphic shown, the segment where the longest orbital period is located at is (DAILY DOUBLE)
What is all or none of them, as they are the same
The orbital period of the moon of an alien planet that orbits at 2.5*10^5 km is 14.4 earth days (the planet has the same mass as earth, 5.97*10^24kg. The orbital period of a satellite that orbits at 9.98*10^3 km is
What is .115 days / 2.76 hours?
The possibility of two objects in space having 0 gravitational attraction towards each other
Apparent retrograde motion is
What is the viewed phenomena of a planet moving backwards in the sky, but is actually the earth (or body the phenomena is observed on) overtaking another planet?
