The four Forces on a Rocket are Lift, Weight, Drag, and Thrust.
Lift is used to take over the weight and to stabilize the rocket. Using the center of pressure, the weight is what makes the rocket land. The drag is directs the object into a direction, such as the fins. Thrust is what is used to make the rocket go up (Usually needs some sort of engine) .
A vector quantity such as force needs a magnitude and direction. A vector quantity is a numerical value of a direction.
The four forces on a rocket are different than those on an airplane. For example: the thrust on an airplane is going horizontal and the lift is going diagonal. Both rockets and airplanes have fins as drag.
The center of pressure is the point where all the aerodynamic forces act upon. It is important because with out it, the rocket would not leave the ground.

Prototype 1
I chose the nosecone shape so the rocket can cut through the air and create less drag for my rocket.
I did not have any fins on my rocket, but if I had the time I would have made 3 right angled triangle fins.
For my Body I used the cylinder shape because I know that it would create less drag for the rocket, and that it looks nice and clean.

This is BOOM the rocket.

Fins are wing like add-ons to increase stability in your rocket. When fins are added to a rocket, the rocket becomes more steady and stable. Fins also are used to direct the rocket straight upwards.
Usually the body is used to carry the fuel or engine, but in our case the body is used to hold the rocket together.
The nose cone is used to create less drag for the rocket and to help the rocket go vertically straight.

Prototype #3
I noticed that the nosecone from prototype #2 was titled a little to the right. I fixed it, by pointing the nosecone straight up and making sure it stays like that throughout the whole flight. It will now fly straight up since I fixed it.
The design for this rocket is two inches smaller than my other prototypes. This draft has a stronger nosecone than the others, as well as a lot more tape than the others. I paid more attention to the nosecone and used 5 layers of tape on top of construction paper. For the body I used 2 layers of construction paper and 5 layers of tape.

My Inquiry Question was: How does the length of a rocket affect how high in the air the rocket will go? I chose that inquiry question because I noticed some bigger rockets flew higher than smaller ones. I was interested in the topic and wanted to investigate it further. I believed that height does not matter when the rocket will be launched. I thought that the center of gravity, fins, nosecone, body and the four forces would matter more than the height. However, I had an open mind, and I was ready to accept any answer. I found that height doesn't really effect the flight of the rocket, as long as the fins and nosecone are proportionate to the body size. I observed smaller rockets and bigger rockets in flight, and height did not play a big role on how high the rockets went. If you are trying to build a successful rocket, remember the following; Don't go for the biggest design, aim for creating the most strong, proportionate, and balanced rocket. Pay attention to how sealed the rocket is and where the center of gravity is. |
