Question

What is the relation between velocity of planet and distance from sun

Answer 1

$\huge\mathbb\fcolorbox{purple}{lavenderblush}{✰αηsωεя࿐}$

That is, the orbital speed of any one planet varies inversely with its distance from the Sun (actually, orbital speed varies inversely with the square-root of the distance, but you needn't worry about that detail).

Answer 2

Answer:

Velocity is inversely proportional to square root of distance

Explanation:

If the planet changes its distance from the Sun as it orbits, then the force of gravity between them must change. If the force that the Sun exerts on the planet increases (as the planet moves closer), then the acceleration of the planet must increase, resulting in a higher orbital speed, and vice versa
