Question

State Kepler's laws of planetary motion.

Answer 1

Kepler's three laws of planetary motion can be stated as follows: All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

Answer 2

Hii dear,


◆ Kepler's Laws of planetary motion-
Kepler described 3 different laws of planetary motion-

1. Kepler’s Law of Orbits –
The Planets move around the sun in elliptical orbits with the sun at one focus.

2. Kepler’s Law of Areas –
The line joining a planet to the Sun sweeps out equal areas in equal interval of time.

3. Kepler’s Law of Periods –
The square of the time period of the planet is directly proportional to the cube of the semimajor axis of its orbit.


Hope this helps you...
