Here's why:
* Newton's Law of Universal Gravitation: This law states that the force of gravity between two objects is directly proportional to the product of their masses. This means if you increase one mass, the force of gravity increases proportionally.
* The Formula: The formula for gravitational force is:
F = G * (m1 * m2) / r²
Where:
* F = force of gravity
* G = gravitational constant
* m1 = mass of object 1
* m2 = mass of object 2
* r = distance between the centers of the objects
* Doubling the mass: If you double the mass of one object (let's say m1), the equation becomes:
F = G * (2m1 * m2) / r²
You can see that the force (F) has now been multiplied by 2.
In summary, doubling the mass of one object will double the gravitational force between the two objects.
