Sorry to ask such a simple question but I appreciate the level of knowldege you guys have.
What is the equation for calculating a single bodies gravity?
What is the equation for calculating a single bodies gravity?
Furthermore, it's only valid for spherically symmetric mass distributions.Nabeshin said:While in Newtonian gravity you treat all an object's mass as if it were located at the center, this assumption is only valid while you are outside of the body.

The equation for calculating the gravity of a single body is F = (G * m1 * m2)/r^2, where F is the force of gravity, G is the gravitational constant (6.67 x 10^-11 m^3/kg*s^2), m1 and m2 are the masses of the two bodies in kilograms, and r is the distance between the two bodies in meters.
The force of gravity is inversely proportional to the square of the distance between two bodies. This means that as the distance between two bodies increases, the force of gravity decreases. For example, if the distance between two bodies is doubled, the force of gravity between them is decreased by a factor of four.
The gravitational constant, denoted by G, is a fundamental constant in physics that represents the strength of the gravitational force between two objects. It is important in the equation for calculating the gravity of a single body because it determines the magnitude of the force of gravity and ensures that the units of the equation are consistent.
Yes, the equation for calculating the gravity of a single body can be used for any two bodies. However, it is most accurate for two point masses (objects with negligible size) and becomes less accurate for larger or irregularly shaped objects.
The force of gravity is directly proportional to the masses of the two bodies. This means that as the masses of the two bodies increase, the force of gravity between them increases as well. For example, if the mass of one body is doubled, the force of gravity between it and the other body will also double.
