Our conclusion.........
The conclusion of this whole project is the quarter fall faster than the feather, and they can’t fall at the same speed by doing experiment.We have using some materials to help us to do the experiment like: a quarter, a feather, a time watch and a measure tape. Then, we have found out the ways that effects the quarter falling faster than the feather. First, is the weight is not the same. Second, is the gravitation, and the last one is the motion. All these can effect the quarter fall faster than the feather. We found these out by following the scientific method.
Our result........
Our result is the quarter fall faster than the feather, by many ways. In our hypothesis , we have guessed right that the feather can't fall in the same speed with the quarter, and we have found out that the quarter is really heavier than the feather.
