Decrease the distance between them.
Increasing the masses of the objects will increase the force of gravity between them. The force of gravity is directly proportional to the product of the masses of the objects. So, by increasing the mass of one or both objects, the force of gravity between them will also increase.
To increase the gravitational force between two objects, you would need to either increase the mass of the objects or decrease the distance between them. Gravitational force is directly proportional to the mass of the objects and inversely proportional to the square of the distance between them.
The magnituide of the gravitational force between two objects will increase if -- the mass of one or both objects increases OR -- the distance between their centers-of-mass decreases.
Increasing the charge on the objects or decreasing the distance between them will increase the electric force between them.
Increasing the mass of the objects or decreasing the distance between them would increase the gravitational force between two objects. The gravitational force is directly proportional to the product of the masses and inversely proportional to the square of the distance between the objects.
The force of gravity between two objects will increase if their distances decrease. The force of gravity or proportional to the objects' masses, and inversely proportional to the square of the distance between them.
At a greater distance, the gravitational force becomes less.
The gravitational force between two objects increases as their masses increase. This is because gravitational force is directly proportional to the product of the masses of the two objects. As the masses increase, the force of attraction between them also increases.
The force of gravity between two objects depends on their masses and the distance between them. Increasing the mass of one or both objects or decreasing the distance between them would increase the force of gravity between them.
The gravitational force between two objects can be increased by increasing the mass of the objects or decreasing the distance between them. It can be decreased by reducing the mass of the objects or increasing the distance between them.
Increasing the mass of the objects or decreasing the distance between them would increase the force of attraction or repulsion between them, depending on the type of force at play (e.g., gravitational, electric, magnetic).
The electrostatic force between two charged objects is inversely proportional to the distance of separation between the two objects. An Increase in the separation distance between objects decreases the force of attraction or repulsion between the objects.
