* Direct Proportionality: The gravitational force between two objects is directly proportional to the product of their masses. This means:
* If you double the mass of one object, the gravitational force doubles.
* If you double the mass of both objects, the gravitational force quadruples.
* Newton's Law of Universal Gravitation: This law mathematically describes the relationship:
* F = G * (m1 * m2) / r²
Where:
* F is the gravitational force
* G is the gravitational constant (a fixed value)
* m1 and m2 are the masses of the two objects
* r is the distance between their centers
In simple terms: The more massive the objects, the stronger the gravitational pull between them. This is why the Earth has a stronger gravitational pull than the Moon, and why the Sun holds all the planets in its orbit.
Example:
Imagine two objects, one with a mass of 1 kg and the other with a mass of 2 kg. If you double the mass of the first object to 2 kg, the gravitational force between them will also double.
