So this project was about connecting Newton's laws to rockets. For the first law it connects to rockets because it stays in a straight line unless acted upon by an outside force. The second law connects to rockets because we can calculate it's net force. And lastly the third law connects because as the rocket is going the gases that come out of the rocket push back at the rocket in conclusion pushing it forward. One fun fact I learned was that when going the rocket does not push off the air, it pushes off its own gases. This will help me in the exhibition because now I can figure out how do this stuff on my rocket.
Within this project the energy that was used was kinetic energy and potential energy. To get the potential energy I have to take the mass, the gravity, and the height. So the equation would look like PE=92g times 9.81 times 9.14 which would equal PE=8249.0328J. Now we have to get the average velocity you have to divide the height by the seconds it took to get to the bottom. So it would look like 9.14m/3.22s to get 2.83850931677m/s. Then finally to get the kinetic energy we have to divide the mass by 2 then square the velocity and then multiply those 2 things together. So it would look like ½(92g)x(2.83850931677m/s)^2 in order to get KE=370.628216504J. The mass impacts the force a lot because the mass decides if it has a big force or a small force, the more mass the object is the more force it will have and the less mass an object has the less force it has. The designs that had the least amount of force were the ones that had the least mass and had the widest parachute, this makes it go a lot slower because of the air drag and the small mass makes it go slower. I think the best design would have been to have the parachute be really wide in order for it to have the most air drag and then for the egg have a hard structure on the outside so the egg does not feel the impact and have a soft thing on the inside like cotton balls in order to make it so the egg is protected and does not move.
We learned a lot this unit, first it started with the properties of matter which includes, mass, volume, and density, then we learn about speed, velocity, and acceleration. Then we learn about Newton's 3 laws and how they applied to rockets, then we learned about all the types of energy. And lastly we learned about kinetic vs potential energy. This unit we did not have a big test just 3 quizzes, on the first quiz I got a 12/15 (meets), then on the next one I got a 10/10 (exceeds), and on the last one I got a 5/5 (exceeds) I got all of those grades because I worked hard on my anchor chart and on going over it. On my anchor chart on a scale of one to ten of effort I put in it I'd say I put in a 5 just like my other ones, I always put a lot of information on them and refined them to make them as good as they could be. Over this whole year we have done 3 anchor charts and I have been trying to improve them each time. On my first one I had no color and my images were not that good and in my next I added way too much color and my images were better but not the best and finally on my last one I did a good amount of color and my images I thought were really good. For high school to prepare myself for tests I will take notes and go over everything that we learned to be the most prepared and confident that I can be.
Overall I learned so much as shown in my anchor chart but I also learned a lot more about rockets and how Newton's laws apply to them. This exhibition was where we launched our own bottle rockets with an egg in it and tried to get the rocket the highest and to make it so the egg survived. Our rocket was called the Pioneer and our egg was named Eggbert. This exhibition was probably the coolest exhibition so far. Overall i got an exceeds because I did way above and beyond on almost everything during this exhibition.
