This week in class we learned about astornomy. We learned that if you shot a cannon off a huge montain and it went fast enough it would orbit the earth. The motion would also be endless like the moon. Then after the two days with the sub we did and experement where you would drop two balls one of heavier mass but they would fall at the same time and hit the ground at the same time. Then we did this with a paper and a rock this will not work because of air resistance. But if this was in a vaccum then the thing would work.
