Yuriy: i think the heavier coin will do more damage kevin: i agree with you yuriy yuriy: yea dude Kevin: yea, the coin with more mass will fall faster and do more damge

Sounds good. I think it's a good idea to film the spot where they hit.

which coins falls faster: 1. We will be using a chip clip to drop the coin. 2. one of us will watch at the bottom to see which coin hits first. 3. we will film the spot where the coins will hit the floor to see for sure which coins falls faster.

"the chip clip was a great way to release the coins at the same time. the weight difference between the coins we believe was not enough to notice the which one fell faster. We measured to our best abilities and it seemed to hit at the same time. even though they hit at the same time the dollar coin made way more damage then the penny. "

the reason why the dollar coin made more damage was because it had a greater mass. Because it had a larger mass it needed a greater force to stop that mass which caused the great dent in the styrofoam.
