I tried yahoo, but I only got one reply, and I don't really have time to make an account with a scientific website, so here is my question.
It is known that the gravitational pull of earth on any mass object will always be 9.8 m/s^2. So basically the mass does not matter on how fast an object falls in free fall. However, I don't really understand why this would always be true, if for example, an object that has a gravitational pull of 10 m/s^2 is 100m next to earth, then that means that that object will actually be pulling earth towards it.
Which implies that the mass of an object does affect the net acceleration, except that the mass of any object on earth is negligible compared to earth.
I know that in F=ma the m cancels and in F=Gm1m2/r^2 the m cancels as well, but it just doesn't make sense to me in a conceptual way.
Hopefully there are some physicist in deviantart that can help me, thanks.
