Question

What is Kepler's law of motion?

Ohh ho
I thought u forgot me like everyone... ​

Answer 1

Answer:

जी कहता जी भर तुझे प्यार करूँ, वक़्त ये कहता क्यूँ तेरा एतबार करूँ, इसी कश्मकश कहीं तुझे खो ना दूं, दिल ये कहता पहले उलझन पार करूँ।

#1 Kepler's First law — The Law of Orbits
According to Kepler’s first law, "All the planets revolve around the sun in elliptical orbits having the sun at one of the foci".

Points to note:
• PERIHELION - The point at which the planet is close to the sun.
• APHELION - The point at which the planet is far away from the sun.

Orbits are elliptical, and from the characteristics of ellipse is the result that the sum of the distances of any planet from two foci is constant.

#2 Kepler's Second Law — The Law of Equal Areas
According to the second law, "The radius vector drawn from the sun to the planet sweeps out equal areas in equal intervals of time."

Points to note:
• Since the orbits is not circular, planet's kinetic energy is not constant.
• More Kinetic Energy near perihelion,
==> More speed at perihelion.
• Less Kinetic Energy near aphelion,
==> Less speed at aphelion.

#3 Kepler’s Third Law — The Law of Periods
Accorsing to the third law, "The square of the time period of revolution of a planet around the sun in an elliptical orbit is directly proportional to the cube of its semi-major axis".

T² ∝ r³

Point to note:
Shorter the orbit, shorter the time taken to complete one revolution.

So, how are you? I've been inactive for so long and now I return, all famous. hahaha! Funny, I know. xD
Just lemme know if you're okay or need help, okay? I'll be here always. :))
