When calculating the gravitational force between two extended bodies, you should measure the distance

When you're calculating the gravitational force between two extended bodies, you should measure the distance: from the center of each body (radius).

Newton's Law of Universal Gravitation states that the gravitational force (force of attraction) acting between planet Earth and all physical objects is directly proportional to the mass of planet Earth, directly proportional to the mass of the physical object and inversely proportional to the square of the distance separating the Earth's center and the center of the physical object.

Mathematically, Newton's Law of Universal Gravitation is given by the formula:

Where:

Deductively, we can conclude that the distance (radius) from the center of each body should be measured when calculating the gravitational force between two extended bodies.
