  1. Physics is involved in pretty much everything in life. Throughout my school day I experience all kinds of physics. First period I have Italian where I sit down (along with the rest of my classes) and I am applying a force to the chair and the chair is applying a force to me because of Newtons third law. Second period when I get my math test score back I hit my head against the desk which is also applying a force to the desk and the desk applies one right back. Third period is art class where I gravity is pushing my eyelids down while I struggle to stay awake. Fourth period is APUSH which could be compared to a black hole. Black holes have tons to do with physics. A black hole is a point in space with so much gravity that not even light can escape and that is most definitely APUSH... Fifth and 6th periods are the best of the day because I do not have classes these periods so I can do my homework. Seventh period is English where I push down on my pencil and it leaves a mark on the many papers I have to write. Gravity also pushes down on that pencil. Eighth period could be the first period of a double for physics or if I am lucky its gym. In gym there is so much physics. A ball is thrown and is a projectile motion. Gravity acts on the ball at all times. If were running in gym we push down on the ground with our legs and the ground pushes us back allowing us to run. And then ninth period, well there is too much physics in a physics class to list. Tons of gravity throughout the day and tons of newtons laws. Crazy..

  2. This is mine and Michalla's catapult. We are excited to launch tomorrow although it does not throw a very far distance. Prior to building it, we did not do any calculations. We built it by eye and what we thought would launch the best. Even though it is not amazing, we are proud of how it came out because at first we never thought us two could build one. If we were to do the project again, we would keep in mine that if it was angled at 45 degrees, it would travel the farthest. Also, if we used some sort of springs we think that the velocity right after the softball leaves the lacrosse stick would be higher. Lastly, from watching lacrosse games I know that lacrosse sticks are often broken. From being in physics class, I now know that all forces come in pairs (Newtons 3rd Law). This has been starting to make me nervous because as the catapult is exerting a force on the softball, the softball is exerting the same force back onto the catapult. If the project wasn't tomorrow I would think about changing what I used to build it for this reason. It should be fun to see what happens tomorrow.
