like in the equation mv^2/r=GmM/r^2 how do we find gravity? so Earth has a gravity of 1? g=f/m? like that?

The equation mv^2/r=GmM/r^2 represents the relationship between the velocity (v) and the distance (r) of an object in circular motion, with the gravitational constant (G) and the masses of the two objects (m and M).
This equation is derived from Newton's law of universal gravitation, which states that the force of gravity between two objects is directly proportional to the product of their masses and inversely proportional to the square of the distance between them. By setting this force equal to the centripetal force (mv^2/r) in circular motion, the equation is derived.
This equation is significant because it allows us to calculate the velocity of an object in circular orbit around another object, based on their masses and the distance between them. It is also useful in understanding the relationship between gravity and circular motion in the universe.
No, this equation is only applicable in situations where circular motion and gravitational forces are involved. It does not apply to other types of motion or interactions between objects.
Yes, this equation can be modified for different scenarios by changing the values of the variables and constants involved. For example, it can be modified for elliptical orbits or for objects with non-uniform mass distributions.
