For Newton’s first law, our hypothesis stated the following: “We can apply Newton’s first law by minimizing the forces that resist motion. The way we will do this is to make the nose cone as smooth and pointy as possible. If the nose cone is too flat on the end, it will not cut through the air very well. The rocket must cut through the air swiftly, this means that resistance will be at its minimum during flight. We would like the least resistance because that means the rocket will glide and not stall mid-air because that will affect flight time.” It’s hard to know if we were correct, because we didn’t have one rocket without a sharp nose cone and one …show more content…
We think that the lighter the rocket, the better it will fly. The mass of a rocket definitely can affect flight time. We can manipulate the amount of paper we put in the head of the rocket to make it heavier or lighter, and we can change how much tape we use to put the rocket together. We want the rocket to glide better in the air, so there is minimum resistance against the atmosphere. We can do this by manipulating the wings and the nose of the rocket and make them straight with a minimal amount of edges. The wings will help guide the rocket in the air and give it direction. The nose of the rocket will be the first part that slices through the air. The nose is an important part because if it is too flat, it will resist the air and make the rocket’s flight time shorter. We are testing how the amount of wings can affect a rocket’s flight time and think that the more wings there, the shorter flight time.” We were correct. The rocket with 3 wings had a flight time of 3.62s with 1 liter of water in it, and 1.29s with 2 liters of water in it. The rocket with 4 wings had a flight time of 3.78 seconds with 1 liter of water, and 1.5 seconds with 2 liters of water in it. So, the three winged rocket did have faster flight time, probably because it was less air resistance. The reason that the rockets performed so poorly with 2 liters of water in them is because that didn’t leave enough room for air, so not much air pressurized and the water didn’t shoot out fast enough. The equal reaction to that was the rocket only going a few meters. So, we can manipulate the build of our rockets to maximize flight time, but we made an error with the water. In the future, we would definitely not put 2 liters of water in the bottle before the launch, we would stick with one. We would find the perfect
