The force of attraction between the two bodies is inversely proportional to the square of the distance between them. As the distance decreases to 1/3 its original value, the gravitational force would increase by a factor of 9.
Q. What two factors determine the strength of the force of gravity between two objects?
Newton’s law also states that the strength of gravity between any two objects depends on two factors: the masses of the objects and the distance between them.

- Objects with greater mass have a stronger force of gravity between them.
- Objects that are closer together have a stronger force of gravity between them.
Q. What happens to the gravitational force between two objects as the bodies become closer to each other?
The gravitational force between two objects becomes weaker if the two objects are moved apart and stronger if they are brought closer together; that is, the force depends on the distance between the objects. The amount of this acceleration is inversely proportional to the mass of the object.
Q. What happens to the force between two charges when the distance is doubled?
The size of the force varies inversely as the square of the distance between the two charges. Therefore, if the distance between the two charges is doubled, the attraction or repulsion becomes weaker, decreasing to one-fourth of the original value. The size of the force is proportional to the value of each charge.
Q. Why is there no life on Neptune?
To find life on Neptune, the planet would need to have a source of energy that bacterial life can exploit, as well as a standing source of liquid water. At its surface, the temperature of Neptune dips down to 55 Kelvin. That’s very cold, and there’s no way liquid water could exist.
Q. Can humans walk on Neptune?
Astronomers have calculated winds blasting across the surface of Neptune at 2,100 km/hour. Deep down inside Neptune, the planet might have an actual solid surface. In short, there is simply no way one could stand on the “surface of Neptune”, let alone walk around on it.
