Question

Or
Write all three Laws of kepler's planatory motion.​

Answer 1

Answer:

The three laws state that: The orbit of a planet is an ellipse with the Sun at one of the two foci. A line segment joining a planet and the Sun sweeps out equal areas during equal intervals of time. The square of a planet's orbital period is proportional to the cube of the length of the semi-major axis of its orbit.

Answer 2

Kepler's laws

1. According to this law, all the planets move in elliptical orbits with the sun situated at once of the foci of the ellipse.
2. The speed of planets varies in such a way that the radius vector drawn from sun to a planet sweeps out equal areas in equal interval of time. (i.e. The areal velocity of the planet around the sun is constant.
3. According to this, the square of the time period of revolution of a planet around sun is proportional to the cube of semi-major axis of its elliptical orbit.
