How would gravitational force change if both object's mass were doubled?

Answer 1

Nice question!

Let's take those one step at a time:

-- Start with a gravitational force of ' F ' between two masses.

-- Double the mass of one object. The product of the masses doubles.

The force changes from ' F ' to ' 2F '.

-- Double the mass of the other object. The product of the masses doubles again.

The force changes from ' 2F ' to ' 4F '.

-- Double the distance between the centers of the objects.

The force is multiplied by 1/22 = 1/4 .

The force changes from ' 4F ' to ' F '.

The force ends up the same as it was before things began to change.

Answer 2

Since the force of gravity between two objects is proportional to the product of the two masses, if both doubled in mass, the force of gravity between them would be 4 times the original gravitational force.

Answer 3

If the masses of both objects were doubled, the gravitational force between them would increase four times. This is because gravitational force is directly proportional to the product of the masses of the objects. Therefore, doubling the mass of both objects would result in a quadrupling of the gravitational force between them.

Answer 4

f = -G * m1 * m2 / r^2, so if the other mass is unaffected, and the distance remains unchanged: f = k * m1 Double m1 and you double f

Answer 5

In that case, the gravitational force doubles as well.

Answer 6

Gravitational force = G x m1 x m2 / r2, therefore, in this case, the force would increase by a factor of 2 x 2 = 4.
