The formula for calculating the gravitational force between two equal masses is F = G(m1m2)/d^2, where G is the gravitational constant (6.67 x 10^-11), m1 and m2 are the masses of the two objects, and d is the distance between them.
The gravitational force between two equal masses is inversely proportional to the square of the distance between them. This means that as the distance between the objects increases, the force of gravity decreases.
The unit of measurement for gravitational force is Newton (N). This unit is named after Sir Isaac Newton, who first described the law of universal gravitation.
No, the gravitational force between two equal masses can never be zero. As long as the two masses exist, there will always be a force of gravity between them, even if it is very small.
The gravitational force experienced by an object is directly proportional to its mass. This means that the greater the mass of an object, the greater the force of gravity it experiences from another object of equal mass.
