The orbit of a planet is an ellipse, with the Sun at one of the two foci
What is Kepler’s 2nd law ?
A line segment joining the Sun to a planet sweeps out equal areas in equal times intervals
Explain the diagram related to Kepler’s 2nd law ?
Areax = Areay when the time between AB = time between CD
What is the consequence of Kepler’s 2nd law ?
The planet moves faster nearer the Sun and slower further away from it
What is Kepler’s 3rd law ?
The ratio of the squares of the periods of any two planets revolving around the Sun is equal to the ratio of the cubes of their mean distance from the Sun
Kepler’s 3rd law formula
Important formula that derives into Kepler’s 3rd law formula but can also be used to find the mass of a planet
