Will

I will be testing to see which falls faster. However, I will be dropping them individually timing them, recording the time it takes for each to hit the ground. Hypothesis: The dollar coin will fall faster.

Good work.

Actual Testing The first thing I did was drop the Dollar coin and the penny coin individually and timed them. The dollar coin hit the ground (when being dropped from the platform between the first and second floor) after 0.87 seconds. The penny hit the ground after 1.15 seconds. However, a problem with this is that each time I may have held each coin at a slightly different height. To double check, I used the clip to drop them simultaneously. The timer was stopped at 1.39 seconds, but Amir (who was assisting for this part) reported that the dollar coin had in fact hit the ground first.

Conclusion: The dollar coin will in fact fall faster, meaning that it would likely be more dangerous should it fall from a significant height.
