The forces of gravity between two masses are always forces of attraction.
As far as we know now, gravity always draws the two masses towards each
other, and never pushes them apart.

∙ 7y agoThe formula for gravity is based on three things: the product of the mass of the two objects concerned, divided by the square of the distance between them, all multiplied by the garvitational constant G.
Basically, the more mass something has, the larger its force of gravity will be on another mass; an increase in one mass proportionally increases the force.

∙ 12y agoyou need a satellite of mass 10 000 kg to orbit radius 10 000 000 metres from earths centre, the gravitational force (f) on the satellite is :
.
f = (G *earth mass* 10 000) / 10 000 000^2 = 39 860 newtons
.
there is only one orbital velocity at this radius that will cause a balancing centripetal force, this is given by:
.
v = square root (( 39 860 *10 000 000 ) / 10 000)
then v = 6313.48 metres / second at this orbit for balancing force

How are forces related to gravity?
force is related to gravity by its mass (m) times the acceleration of gravity (g) F =mg
What would happen if we didn't have gravity?
Without gravity, none of the stars or planets would maintain their forms. Gravity allows the Sun to maintain its energy generation while remaining as a single mass. Gravity allows the Earth to hold its atmosphere. Indeed, gravity is the force that forms stars and planets, although the trigger that begins the process is still unclear.
Why is gravity vital?
It depends on what you think it is vital for. For life? Almost certainly! If only because gravity is required for the formation of stars and planets.
How is weight related to the force of gravity?
They are one and the same.
What measurements are affected by gravity?
Anything related to weight.
How are stars in a constellation related?
Gravity, proximity, age
Are stars rounded by gravity?
yes because they levitate in space gravity does hold stars up
Do stars twinkle due to refraction or gravity?
Stars in the universe twinkle because of refraction not gravity.
How are stars made with no gravity?
They aren't. Stars form as a result of a cloud of gas collapsing due to gravity.
How does gravity affect the stars moon an planets?
Gravity keeps the planets in orbit around the sun and the stars and the stars in orbit around the center of the galaxy. Gravity also holds the stars together against their own internal pressure.
Which pulling force do planets and stars have?
Planets and stars have gravity.
What force is responsible for holding the stars gases and dust together in a galaxy?
The answer is simple: gravity.
Is there grivity on Jupiter?
There is gravity. There is gravity on all planets, moons, and stars.
How does gravity affect the formation of stars?
Gravity doesn't just "affect" the formation of stars; it's just about the only force that CAUSES the stars to form in the first place.
Did gravity form stars?
Yes. Stars form when clouds of gas and dust, called nebulae, collapse under the force of gravity.
Why do planets orbit stars and moons orbit stars?
Because stars have a greater amount of gravity
Does gravity pull stars into the galaxies?
It might; gravity might also catapult stars out of a galaxy. But mainly, the stars in a galaxy are believed to have formed within the galaxy in the first place.
