NASA Aerospace Institute - Day 5: Today we started rocketry lessons and learned about Newton's three Laws of Motion. We made pop rockets, paper rockets and altitude trackers, which made for much silly fun for all!

Today's factoid: Newton's First Law of Motion states that, "an object in motion continues in motion forever". However friction stops motion and, thus, air will eventually stop motion. Since there is no air in outer space, and thus no friction, a spinning gyroscope put in space will stay in the position that it is put in. For this reason gyroscopes are used to keep satellites and the International Space Station in position. Interesting, eh?
