Question

heyyy ❤️❤️❤️❤️❤️what are Kepler's law​

Answer 1

Answer:

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.

Explanation:

Answer 2

Answer:

Kepler's Three laws are:

1.  Kepler's Law of Planetary Motion.

2. Kepler's Law of Areas.

3. Kepler's Law of Periods.

Explanation:

Kepler's First Law:

      Kepler's First Law of Planetary Motion states that the orbits of planetary bodies are ellipses with the sun at one of the foci of the ellipse.

Kepler's Second Law:

      Kepler's Second Law states that the A radius vector joining any planet to the Sun sweeps out equal areas in equal lengths of time.

i.e,$L=mr^{2}$ω

Kepler's Third Law:

      Kepler's Third Law states that , "The Square of the Orbital period of a planet is directly proportional to the cube of semi-major axis of its orbit.

i.e,    $T^{2}$ ∝$r^{3}$

When something is in orbit, Centripetal Force is caused by Gravitational Force.

$[\frac{mv^{2} }{r} =G\frac{Mm}{r^{2} }] +[v=\frac{2πr}{T} ]\\\frac{T^{2} }{r^{3} } =const$

so  $T^{2}$ ∝$r^{3}$
