On what properties does the force of gravity between two objects depend?

Answer 1

The strength of a gravitational field at any given point is proportional to the planetary body's mass and inversely proportional to the square of the distance from the center of the body.

Answer 2

Primarily the size of the Objects and the distance between them - the relationship between them is given by:

F = G (m1 * m2 ) / r2

note: You just divide the "m"s by r2

where m1 and m2 are the masses of the two objects, r is the distance between the two objects and G is the gravitational constant (6.67 x10^-11)

Answer 3

Without delving into Einstein's General Relativity, Newton's law of gravitiation is the starting point: F=GMm/r^2

F = force felt (in Newtons, 1kg weighs approximately 10N on Earth) (by either body since by Newton's 3rd law of motion the force exerted on one body by the second must be the same as the force the first exerts on the second)

G = gravitational constant = 6.67e-11 m^3/kg/s^2 (0.0000000000667 if you don't know standard form)

M = mass of one body (in kg)
m = mass of other body (in kg)

r = distance between the bodies (in metres)

Answer 4

-- the product of their masses

-- the distance between their respective centers of mass

Answer 5

both masses, and the square of the distance between both centers of mass

Answer 6

Gravity is dependant on: Mass of object/s and their distance/s.

Answer 7

The force of gravity depends on the velocity field, the mass and the separation distance, F = vp/r = mv2/r.
