<font color="yellow">Everyday experimentation verifies this equality: Two objects (one heavy and the other one light) “fall” at the same speed. Yet, the heavy object is more attracted by Earth than the light one. So, why doesn’t it fall “faster?” Because its resistance to acceleration is stronger. From this, we conclude that the acceleration of an object in a gravitational field doesn’t depend upon its mass. Galileo Galilei was the first one to notice this fact. It is important that you should understand that the fact that all objects “fall at the same speed” in a gravitational field is a direct consequence of the equality of inertial and gravitational masses (in classical mechanics).</font><br /><br />Umm.<br /><br />Suppose you have a rock and plate just above earth. Both fall at 9.81 m/s^2<br /><br />Ok....<br /><br />Suppose you have a rock and a sun just above earth. Do both fall at 9.81 m/s^2 ????????<br /><br />It seems to me that the free fall acceleration of two objects is really the sum of their individual accelerations.<br /><br />Thus:<br /><br />Acceleration = GM/r^2 + Gm/r^2
