How does the size and distance of two objects affect gravitational pull and apparent magnitude of the objects?

-- The size of the objects has no effect on the gravitational forces between them.
The magnitude of the forces depends on the product of their masses, which are
not necessarily related to their size.
-- The gravitational force between them decreases according to the square of the
distance between their centers. That means that if the distance doubles, the force
becomes 1/4 as great, and if the distance multiplies by 5, the force becomes 1/25 as great.
-- I don't understand what is meant by the "apparent magnitude of the objects".
==========================
Oh, wait! Don't go away. Are you talking about the apparent brightness of a star
as its distance from us changes ? (There I go again ... changing an incomprehensible
question into one that makes sense, before I start laboring to answer my own question.)
-- The apparent brightness of a light source acts according to the same "inverse square"
law as the gravitational force does.
-- Each "magnitude" of brightness of a sky object is actually a ratio of 2.1544 .
(The 6th root of 100 . . . Don't ask!)
-- So if I'm handling this correctly, that means that every time you move a star
about 1.4678 times farther from us, it appears less bright by 1 magnitude.

What happend to the gravitational force between two objects if the distance between them is decreased?
The gravitational force that one object exerts on another will decrease in magnitude. In the formula for gravitational force, the force is inversely proportional to the square of distance. This means that reducing the distance between the objects will increase the magnitude of gravitational force.
What affect the magnitude of gravitational force?
Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.
What affects the magnitude of gravitational?
Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.
Does the magnitude of a gravitational force depend on the distance of an object from another object or the size and distance of objects from each other?
The mass and distance of an object fom another object
What does the apparent motion of objects in the sky depend?
The apparent motion of objects in the sky depends on the motions of Earth.
What are two things that affect the magnitude of gravitational force?
The mass of the objects and the distance between them.
What affect the magnitude of force?
Gravitational Force = Gravitational Constant x mass of the first object x mass of the second object / distance squared. So what affects the magnitude is the masses of the objects and the distance between them. Gravitational Constant = 6.672 x 10^-11 N x m^2/kg^2 Both masses, and the distance between them.
How does mass affect the magnitude of gravitational force?
The magnitude of gravitational force between two objects is directly proportional to the product of their masses. This means that as the mass of one or both objects increases, the magnitude of the gravitational force between them also increases. In simpler terms, the more massive an object is, the stronger its gravitational pull.
What two things between objects do the force of gravity depend on?
The magnitude of the gravitational force between two objects depends on-- The product of their two masses-- The distance between their centers of mass
Does distance between objects effect the gravitational attraction between them?
Yes. At a greater distance, the gravitational attraction between two objects is less.
What two things determine the force of gravity between two objects?
The magnitude of the mutual gravitational forces between two objects is determined by the masses of the objects and the distance between their centers. "Their centers" above seems to hold for spherical objects, but you need to integrate the distances between the masses.
Would the apparent magnitude of the sun increase or decrease if it were farther away from Earth?
The numeric value of the apparent magnitude would increase, since bright objects have lower magnitude values than dim objects.To give some actual numbers as an example: the Sun has an apparent magnitude of about -27. It is much, much brighter than the moon, which at its brightest has an apparent magnitude of -13 or so.
