Preculmintaion Prep.

Today I explored parachutes and catapults (like the one I used yesterday). It was fun because when I used the catapult, my object, which was a small motor landed in the same spot several times, and it was successful. Then I took notes on Anna's catapulting. We figured if the object is at more of a vertical angle, it will be more accurate, than at a horizontal angle. We also took not on the difference between air-resistant objects, and non air-resistant objects.

Some questions I have:
1. What makes objects more or less air-resistant?
