Why does doubling the mass of an object double its weight, but doubling its distance from the center of Earth reduces its weight fourfold? The weight is equal to the gravitational force between the object and Earth, and the gravitational force is inversely proportional to the distance squared between the object and Earth. The weight is half the gravitational force between the object and Earth. The weight is two times the gravitational force between the object and Earth. The weight is directly proportional to the square of the gravitational force between the object and Earth.

Centripetal Force

A particle, body, object or certain mass while travelling in a rotational path or semicircular path, experiences an inertia force. If that inertia force pulls the towards the inward of the imaginary circle in the rotation, it is termed as centripetal force.
