Question

What do we mean by keplers law of planetary motion?; What do we mean by keplers law of planetary motion?

Answer 1

__________________________
Kepler's laws of planetary motion are three scientific laws describing the motion of planets around the Sun. The orbit of a planet is an ellipse with the Sun at one of the two foci.
__________________________

✴Kepler’s three laws of planetary motion are:-

[1] All planets move about the Sun in elliptical orbits, having the Sun as one of the foci.

[2] A radius vector joining any planetto the Sun sweeps out equal areas in equal lengths of time.

[3] The squares of the sidereal periods (of revolution) of the planets are directly proportional to the cubes of their mean distances from the Sun.

Kepler's Law➫ A law state that the orbit of each planet is an ellipse with the sun at one focus of the ellipse.

▸ This law is also known as - Kepler's Law 0f Planetary Motion.

➧The Kepler's Laws are:-▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃▃⤵

❶❫ Laws 0f 0rbit:-▬▬▬▬▬▬▬▬▬▬☟

Every planets revolves around the sun in an Elliptical 0rbit with the Sun situated at one of the foci of the ellipse.

❷❫ Laws 0f Area:-▬▬▬▬▬▬▬▬▬▬☟

Each planets moves in a such a way that an imaginary line drawn from the sun to the planets sweeps out equal area in equal intervals of time.

❸❫ Laws 0f Time Period:-▬▬▬▬▬▬▬▬▬▬▬☟

The square of the orbital period of a planet is proportional to the cube of the semi-major axis of its 0rbit.
