No, the force of gravity between two objects does not decrease with distance. According to Newton's law of universal gravitation, the force of gravity is directly proportional to the product of the masses of the two objects and inversely proportional to the square of the distance between their centers. Mathematically, the equation is expressed as:
F = G * (m1 * m2) / r^2
Where: F is the force of gravity G is the gravitational constant m1 and m2 are the masses of the two objects r is the distance between their centers
As you can see from the equation, the force of gravity decreases as the distance between the objects increases, but it does not decrease due to a decrease in the "mass of gravity." The mass of an object remains constant, and the force of gravity is determined by the masses of both objects and the distance between them.
In simpler terms, as two objects move farther apart, the gravitational force between them becomes weaker because the effect of gravity diminishes with distance. However, the mass of gravity itself does not decrease.
