What is the relationship between orbital speed and the mass of the attracting body mass of the orbiting bodyand distance between the two?

Answer 1

The gravitational force varies directly as the mass and inversely as the square of the distance.

Answer 2

Mass increases with speed, though significantly only at relativistic speeds. I can't get this to accept math symbols, so I'll spell it out the long way: m = mo /square root of [1 - (v2/c2)] where mo is the rest mass v is velocity c is the speed of light

Answer 3

This is the universal law of gravitation.

F = (m1)x(m2)xG/(d^2)

Grav. force is directly proportional to the product of the 2 masses and inversely proportional to the square of the distance between their centers. F is force, G is the universal grav. constant, m1 mass of 1st object, m2 mass of 2nd, d is distance between their centers.

Answer 4

"Entirely coincidental" is possibly the best description. There is no clear connection between planetary mass and number of satellites:

* Venus is almost the same mass as Earth but has no satellites to Earth's 1. * Mars is half the mass of Earth but has two satellites. * Jupiter has 60 or so; Saturn, significantly less massive than Jupiter, also has about 60. * Uranus has 27 (that we know about); Neptune, which is almost the same mass, has only 13 (again: that we know about). * Pluto (which is no longer considered a planet) has at least three satellites despite being much less massive than Mercury, which has none.

Answer 5

I believe the attracting cohesive force is directly proportional to the product of their mass divided by the sum of the distance between them?

Answer 6

The orbital period is caused by the orbital speed, for instance: Earth's year is consistent of 365 days, but, if we were any slower our orbital period or year will be longer.
