Question

Which change will always result in an increase in the gravitational force between two objects? increasing the masses of the objects and increasing the distance between the objects decreasing the masses of the objects and decreasing the distance between the objects increasing the masses of the objects and decreasing the distance between the objects decreasing the masses of the objects and increasing the distance between the objects

Answer 1

Increasing the masses of the objects and decreasing the distance between the objects

Answer 2

By definition, we have that the gravitational force is given by:

$F = \frac{G * m1 * m2}{r ^ 2}$

Where,

G: gravitational constant

m1: mass of object number 1

m2: mass of object number 2

r: distance between both objects.

Therefore, for the gravitational force to increase, the following conditions must be met:

1) Increase the mass of the objects so that the numerator of the equation is greater.

2) Decrease the distance between the objects so that the denominator of the equation is smaller.

Answer:

A change that will always result in an increase in the gravitational force between two objects is:

increasing the masses of the objects and decreasing the distance between the objects
