How does gravity affect distance?
Gravity does not affect distance, gravity has nothing to do with distance. However, the effect of gravity decreases with increase in separation.
Mass and distance affect the force of gravity between objects. The way these two variables affect the force is that gravity is directly proportional to mass. Double the mass and you double the force of gravity generated by a given object. Gravity is inversely proportional to the square of the distance between objects. If you double the distance between objects, only one quarter the gravity will be present. Halve the distance and four times the…
The mass of each object will affect the force of gravity between the two objects, and the distance between the objects will affect the force of gravity between the two objects. The more mass that is involved, the greater will be the gravimetric force, and the smaller the distance between the objects, the greater will be the force. For smaller mass and greater distances of separation, there will be less gravity.
The greater the mass the stronger the gravitational pull. You probably mean the "surface gravity". This is also affected by the distance of the surface from the center of the planet or Sun. The strength of the gravity falls in proportion to the distance squared, in accordance with Newton's Law of Gravity.
The farther apart two objects are, the less the gravitational force between them. Gravity gets weaker with distance. To be specific, it decreases by the square of the distance. If you double the distance (multiply the distance by 2), the force of gravity is 1/22 or 1/4th as great as it was. If you triple the distance, the force is 1/32 or 1/9th as great, and so on.
Is it true that Gravity exists between two objects but only when they're close enough to affect each other?
Increase mass, increase gravity. Increase distance, decrease gravity (although you never reach zero). The formula for calculating force of gravity is: Fg=(G*m1*m2)/d^2 where Fg is force of gravity, G is the universal gravity constant, m1 and m2 are the masses of the two objects, and d is the distance between the two objects
