We keep getting drilled with the info in class that all objects would fall to the earth at the same speed. And it does not make sense to me So the equation is (Ge * m1 * m2)/r2 = F And F = m1 * a. There fore m1 * a = (Ge* m1*m2)/r2 This can be simplified and the m1 eliminated by dividing it from both sides, so that a = Ge *m2(mass of earth)/r2. So my question is, how does this work with masses larger than the earth? Because according to this equation the only thing determining acceleration is the mass of the earth and the distance and the the Gravitational Constante Ge. Do you just use the mass of the larger object to calculate acceleration and disregard the smaller object's mass?
