<p>1.) When you push on an object, how does the magnitude of the force affect its motion? If you push harder, is the change in motion smaller or larger? Do you think this is a direct or inverse relationship?</p>

<li><p>Assume that you have a bowling ball and a baseball, each suspended from a different rope. If you hit each of these balls with a full swing of a baseball bat, which ball will change its motion by the greater amount?</p></li>
<li><p>In the absence of friction and other forces, if you exert a force, F, on a mass, m, the mass will accelerate. If you exert the same force on a mass of 2m, would you expect the resulting acceleration to be twice as large or half as large? Is this a direct or inverse relationship?</p></li>

<p>just remember that heavier objects fall faster, an object's natural state is obviously being at rest, and that Claudius Ptolemy's model of the universe is precise. You don't want trouble with the Inquisition, now do you? Ask Galileo. Foolish man he was.</p>

<p>heavier objects don't fall faster</p>

<p>all objects at the earths surface are being pulled by the same gravitational force, 9.8m/s^2
so a feather would fall as fast as a 1 ton man</p>

I don't think you quite got his post, heh.</p>
