Question

The force of gravity between two objects: The force of gravity between two objects: depends on the density, not the mass of the bodies. depends on the temperature, density, and size of the bodies. increases with the masses of the bodies, but decreases with their separations. increases with the square of their masses, but decreases with the cube of their periods of orbit about the Sun. increases with the masses of the bodies, but decreases with the square of the distances between them.

Answer 1

Answer: increases with the masses of the bodies, but decreases with the square of the distances between them.

According to Newton's law of Gravitation, the force
`F` exerted between two bodies or objects of masses
`m1` and
`m2` and separated by a distance
`r` is equal to the product of their masses divided by the square of the distance:

`F=G((m1)(m2))/(r^2)`

Where
`G`is the gravitational constant.

As we can see, this force is directly proportional to the product of the masses and inversely proportional to the square of the distance between them.

This means that the gravity force decreases when the distance between these two bodies increases, and increases when the masses of the bodies increases.
