Kepler’s Laws

Observe the given figure showing the orbit of a planet moving around the Sun and write the three laws related to it:

The orbit of a planet moving around the Sun

The orbit of a planet revolving around a star is _______.

Let the period of revolution of a planet at a distance R from a star be T. Prove that if it was at a distance of 2R from the star, its period of revolution will be \[\sqrt{8}\] T.    

The square of its period of revolution around the sun is directly proportional to the _______ of the mean distance of a planet from the sun.

Observe the given figure and answer these following questions.

1. What is the conclusion about the orbit of a planet?
2. What is the relation between velocity of planet and distance from sun?
3. Explain the relation between areas ASB, CSD and ESF.

Write the Kepler's laws.

Identify the law shown in the figure and state three respective laws.
