Kepler's Laws Of Planetary Motion | Gravitation | Class 11 Physics
Kepler’s Laws
Kepler’s Laws for planetary motion is found by Johannes Kepler and it can be derived as,
Kepler first law – The law of orbits
Kepler’s second law – The law of equal areas
Kepler’s third law – The law of periods
We can illustrate it in detail as below,
Kepler's First Law
Kepler’s first law states that, All planets move around the sun in elliptical orbits with the sun at one focus.
Kepler’s Second Law
Kepler’s second law states that, the line joining a planet to the Sun sweeps out equal areas in equal interval of time.
Kepler’s Third law
Kepler’s third law states that, the square of the time period of the planet is directly proportional to the cube of the semimajor axis of its orbit.
All the above-mentioned topics are described in an interactive and efficient manner so that the students could easily understand them.
