If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

But gravity only becomes noticeable when you have at least one very big mass (a planet for example). No, the distance is squared in the equation so it would have nine times the force (a third of ...

The weight of an object is the force on it due to the gravitational pull of gravity at that point ... g\)) of a planet is the weight per unit mass of an object on that planet.
