If Vo is the orbital velocity then the centrifugal force is m Vo2/ R+h where R is the radius of the earth and h is height of the body of mass m orbiting around the earth.
The force of attraction between earth and body is G M m /(R+h)2 G is the universal gravitational constant and M is mass of the earth.
For equilibrium the gravitational force will be equal to the centrifugal force.
So Vo = sq root of GM/(R+h)
But GM = gR2 g is acceleration due to gravity.
So Vo = sq root of g R2/R+h
When h is very much smaller compared to R then neglecting h
we get Vo = sq root of gR
So orbital velocity is directly proportional to the square root of acceleration due to gravity.
The Moon is orbiting a planet; It is orbiting the Earth. The velocity /acceleration of the Moon and the gravitational pull between Earth and Moon are in balance, so the Moon remains orbiting the Earth. Similarly the Earth and Moon , as a binary system, orbit the Sun , and the acceleration and gravitational forces are in balance. So none of us collide.
As far as I know, there is no simple relationship between the two. Not much is known yet about planets orbiting other stars, so I don't think there are sufficient statistics about this either.
Yes, the satellite is accelerating because it is revolving around our earth and in a circular motion so its velocity changes every second so it is accelerating.A2. No, the satellite is not accelerating. Acceleration is defined as the rate of change of velocity. But, its velocity is constant. The centrifugal effect is exactly balanced by the pull of gravity (assuming a circular orbit).But a nice question. The net acceleration between these forces is zero.
WikiAnswers cannot support diagrams - sorry. A satellite around the Earth will have an elliptical or (in some cases) a circular orbit. The satellite is constantly accelerating towards the Earth due to the gravity between the Earth and the satellite. However, because of the satellite's tangential velocity, it stays at a relatively constant distance from the Earth.

Regarding their magnitudes . . . Acceleration is the time rate of change of velocity. Regarding their directions . . . There's not necessarily any relationship between the two.
Acceleration is the rate at which velocity changes and the direction of the change.
Momentum=mass*velocity
Acceleration is the rate of change of the magnitude of velocity and the direction in which the velocity changes.
Momentum=mass*velocity
Acceleration is the rate at which velocity changes.
Acceleration is the rate of change of velocity.

Velocity is distance over time, Acceleration is velocity with a direction.
Speed is a measure of motion and velocity just includes what direction it happens in.Acceleration is a measure of changes in speed.
Acceleration is change of velocity per unit time. Acceleration =(v2 - v1)/t. It is also related to force and mass: F = ma.
