So this mini-project has actually been proven before, but I still have some doubts to it - do paper and a bowling ball both land at the same time when dropped from a certain height?
For this mini-project, you will need two materials , preferably of a different weight; in this case, I chose:
1. A small styro-foam soccer ball
2. A Washington - one dollar bill
Science:
-Gravity is a field force, or a force that pulls you even if you are at a great distance
-equivalence principle (key): a principle explored by researchers such as Galileo and Einstein that said two objects of a different mass or vacuum composition dropped from a certain height will fall and land at the same time.
My Three Tries:
1) the dollar seemed to hit the ground after the ball; my guess is that since the dollar bill was bent, the friction of air slowed it down.
2) after smoothing the bill out, the time that both objects hit the ground seemed more even.
3) they both hit the ground at the same time! success!
here is Galileo's falling objects lab proven by "mysciences":
