Question

(Satellite Simulation)

Theory: State Kepler’s laws of planetary motion (all three). Include the diagrams and formula as well.

Answer 1

Keppler’s laws of planetary motion

These are empirical laws (not based on theory based on experimental result)

Ist law :- All planets move around the sun in elliptical orbit. With sun being located at one pf the foci of ellipse

Observation was done by Tychobrahe and analysis of data was done by Keppler.

2^nd law :- Areal velocity of all planets around the sun is constant. In other words area swept by radical line per unit time is constant

Areal velocity is constant for all central force but orbit will be elliptical
