If you replace m with M, yes.is one of them g=Gm/r^2
The equation for gravitational force between two objects is F = G(m1m2)/r^2, where F is the force, G is the gravitational constant, m1 and m2 are the masses of the objects, and r is the distance between them.
The force of gravity is inversely proportional to the square of the distance between two objects. This means that as the distance between two objects increases, the force of gravity between them decreases.
Gravitational field strength is a measure of the force experienced by a unit mass at a given point in a gravitational field. It is represented by the symbol g and is measured in units of meters per second squared (m/s^2).
Gravitational field strength is calculated by dividing the force of gravity (F) by the mass of the object (m) at that particular point in the field. In equation form, it is written as g = F/m.
The mass of an object does not affect gravitational field strength. The gravitational field strength at a given point is only affected by the mass of the object creating the field and the distance from that object.
