In this Science (Physics) video in Hindi for Class 9 we explained Kepler's laws of planetary motion. This is a topic from Chapter 10 - 'Gravitation' for class 9th from NCERT.

Kepler's laws of planetary motion are following

1. The orbit of a planet is an ellipse with the Sun at one of the foci.
2. The line joining the planet and the Sun sweep equal areas in equal intervals of time.
