Question

State and explain kepler's three laws of planetary motion

Answer 1

Explanation:

Kepler's three laws of planetary motion can be stated as follows: (1) All planets move about the Sun in elliptical orbits, having the Sun as one of the foci. (2) A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

Answer 2

Explanation:

Kepler ,s Law of planetary motion:

i. THE LAW OF ORBIT :

Each palnet revolves around sun in elliptical orbit with sun situated at on end of two foci.

ii. LAW OF AREA :

The radius of vector drawn from the sun to a planet sweep out equal area in equal interval of time means Areal velocity remain constant.

iii. LAW OF PERIOD :

The square of the period of revolution of a planet around the sun is proportional to the cube of semi major axis of its elliptical path.
