Select the two variables that affect the strength of gravity between objects.

1 answer

The two variables that affect the strength of gravity between objects are:

  1. Mass of the objects: The greater the mass of the objects, the stronger the gravitational force between them. This relationship is described by Newton's law of universal gravitation, which states that the gravitational force is directly proportional to the product of the masses of the two objects.

  2. Distance between the objects: The gravitational force decreases as the distance between the centers of the two objects increases. Specifically, the force is inversely proportional to the square of the distance between the objects. This means that if the distance doubles, the gravitational force becomes one-fourth as strong.

In summary, the strength of gravity is affected by the mass of the objects and the distance between them.
