Question

Explain the Kepler's law of gravitation.

Answer 1

Kepler's three laws of planetary motion can be described as follows:
The path of the planets about the sun is elliptical in shape, with the center of the sun being located at one focus. (The Law of Ellipses)
An imaginary line drawn from the center of the sun to the center of the planet will sweep out equal areas in equal intervals of time. (The Law of Equal Areas)
The ratio of the squares of the periods of any two planets is equal to the ratio of the cubes of their average distances from the sun. (The Law of Harmonies)
Kepler's Laws of Planetary Motion
1.The planets travel in ellipses with the Sun at one focus
2.The radius vector sweeps out equal areas in equal times $(A_1=A_2)$
3. The square of the period of revolution, T, is proportional to the cube of the mean distance, \((R(T^2=R^3))
