Afamous instance of variation is newton’s law of gravity. it states that the magnitude of the force, f, of gravitational attraction between two masses, m1 and m2, varies directly with the product of the masses and inversely with the square of the distance, r, between them. write a variation equation relating f, m1, m2, and r.
