Here's why:
* Gravitational force depends on mass and distance: The gravitational force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between their centers.
* Density is mass per unit volume: While density tells us how tightly packed the mass is, it doesn't change the total amount of mass.
Example:
Imagine you have two spheres, both with the same mass (say, 1 kg). One is made of lead (high density), and the other is made of foam (low density). They will have the same gravitational pull on another object because they have the same mass. The only difference is that the lead sphere will be much smaller in size.
In summary: Gravitational pull is determined by mass, not density. While density impacts the volume of an object for a given mass, it doesn't change the object's gravitational influence.
