|
|
One Revolution

|
When it is farthest from the sun
When does a planet move the slowest?
|
Inertia

|
p^2 = a^3
What was the equation that Kepler came up with in his third law?
|
|
Orbit
What is the path that one body follows along another body?
|
The farther the planet is from the sun, the longer it will take to make one revolution.
How is a planet’s distance from the sun related to the amount of time that it takes for planet to make one revolution around the sun?
|
Mass increased = Force increased
Distance increased = Force decreased
