Theres a question on my homework that i dont understand. It says : Explain the relationship between the force of gravity and the mass of the two objects and the distance between them.

What two objects? Theres nothing indicating any specific objects. How can i explain this answer?

"Why do mass and distance affect gravity?
Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. This relationship was first published by Sir Issac Newton. His law of universal gravitation says that the force (F) of gravitational attraction between two objects with Mass1 and Mass2 at distance D is:

F = G(mass1*mass2)/D squared.

(G is the gravitational constant, which has the same value throughout our universe.)


Einstein's theory of relativity adds to this. His theory predicted that objects with great mass deform space around them, causing light to deflect into them. That has been shown to be true. He also predicted that gravity could travel in gravity waves, which we haven't seen yet.

None of this explains why mass or distance affects gravity, though. To do that, we must look at the theories of scientists more recent than Einstein. According to theory, the reason mass is proportional to gravity is because everything with mass emits tiny particles called gravitons. These gravitons are responsible for gravitational attraction. The more mass, the more gravitons.

Graviton theory also accounts for differences in gravitational attraction over distances. Most gravitons exist in a cloud around the object. As distance from the object increases, the density of the graviton cloud goes down, so there is less gravitational attraction.

It don't mean to specify any type of object. In general, it just wants you to grasp the relationship between gravity, mass and distance. Gravity is almost = mass and distance between objects.

Here's what I got from a link: Gravity is a fundamental underlying force in the universe. The amount of gravity that something possesses is proportional to its mass and distance between it and another object. This relationship was first published by Sir Issac Newton. His law of universal gravitation says that the force (F) of gravitational attraction between two objects with Mass1 and Mass2 at distance D is:

F = G(mass1*mass2)/D squared.
