The force of gravity is twice as great on a 2-kg rock on a 1-kg rock. Why does the 2-kg rock not fall with twice the acceleration?

Stargate said:They both have the same mass and acceleration! Right?
The force of gravity is a fundamental force of nature that attracts objects with mass towards one another. It is responsible for the motion of celestial bodies, as well as the acceleration of objects near the Earth's surface.
The force of gravity is calculated using Newton's Law of Universal Gravitation, which states that the force between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them.
The acceleration of a 2-kg rock due to gravity is approximately 9.8 meters per second squared near the Earth's surface. This means that the rock will increase in speed by 9.8 meters per second for every second that it falls.
The force of gravity decreases as the distance between two objects increases. This is because the inverse square law states that the force is inversely proportional to the square of the distance between the objects. Therefore, the force decreases exponentially as the distance increases.
The force of gravity cannot be shielded or cancelled by any known means. However, objects can appear to have no weight when they are in free fall, as they are experiencing the same acceleration as the surrounding environment.
