Now that physics has come to an end, I understand a ton of information that will now always spark into my mind on a daily basis just by doing normal things. For instance when ever I throw a baseball I can't he but to think about different factors in projectile motion, like why does the ball fly the way it does and how can I get the ball to go the farthest with the right angle. Physics is everywhere and in everything and if you know a little physics then you will notice it a lot.
This year we learned about all kinds of physics concepts and we did all kinds of experiments. Some of my favorite topics were the topics that made me think like quantum physics. I also loved our projectile motion unit because at the end of the unit we got to build catapults.
My catapult was a mixture between a spring firing catapult and a trebuchet. The way a trebuchet works is by heavy weight dropping to rotate the catapult arm swinging a long sling and propelling an object. Instead of the weight, my group decided to use springs and bungee cords to put the arm and sling into motion with great force and it truly worked better than we expected.
The first test shot went over 60 meters, but being the way I am, I had to see if it would go farther. Joe F. and I changed the sling release angle to as close to 45 degrees as possible to see if it would make the softball go farther. We also experimented with other objects like apples and baseballs. The apples flew very inconsistent and the baseballs flew very far, much farther than the softball because off the less air resistance. We also tried making a baseball wet and heavy to see if it would change the distance but it didn't change much at all.
On the day of launch my group, Roxy, Joe, Andrés and I broke the school record and launched a softball a whopping 82 meters. I didn't now that it was going to go that far. I learned that if you put in 110% effort, anything is possible to achieve. This was a very fun and memorable part of my physics year. Thank you Mr. Fullerton for a great year of physics class!
