CO2 dragster
Planning (Conceptual Model):
Identify the Problem:
-To design and build the quickest and most aerodynamic CO2 dragster possible.
Generate Ideas:
-The wheels must align correctly with the body of the dragster. The car should have thin wheels in the front, and thick wheels in the back.
-The body must be effective (such as a long or short body, or even a narrow and a wide body)-
-The car must be as low to the ground as possible to create the most speed.
-Have the car to weigh light and not heavy so it can move pretty fast.
-The bump at the back is used of air resistance.
Constraints:
Criteria:
-Speed:
-the rate at which someone or something is able to move or operate, also it is the rapidity of movement or action. The faster the better
-Weight:
-a body's relative mass or the quantity of matter contained by it, also it is the heaviness of a thing. The heavier the dragster the harder it will produce speed and go fast.
-Balance:
-an even distribution of weight enabling something to remain upright and steady. The car has to be balanced in order for it to work properly. If its too heavy on one side the weight will either tip it over and make it hard for it to move.
-Aerodynamics:
-the study of the properties of moving air, and especially of the interaction between the air and solid bodies moving through it. The dragster has to be aerodynamic friendly because the solid (car) and the air (CO2) has to interact in a positive way.
Research:
Theoretical:
- There are 4 basic principles for force:
-Mass: the less weight = the faster it goes
-Thrust: the gas escaping the from the CO2 cartridge the car
-Friction: the dragster has parts moving against each other
-Drag: the air resistance as increases, it pushes against your CO2 car and prevents it from going fast as it could
-Drag is the hardest principle to deal with because the air is pushing against it and it is very hard for it to go its top speed.

"The Big Drop"
"The Sharp One"
The Idea Matrix:
Summary:
I choose the "sharp car" because it will produce the greatest amount of speed, it is the lightest, and supports the theory of aerodynamics the best, comparing to all of the other possible solutions.

Mathematical Model:
According to the Constraints Sheet and looking over the data provided, the people in red are the cheaters and in the people in black are the non-cheaters
This graph is comparing the weight and the length of the CO2 Car.
On the X-Axis is the length of the CO2 Car and on the Y-Axis is the weight of the CO2 Car. Both graphs contain the "cheaters" and the "non-cheaters" list's.

What makes a fast CO2 Car?
To make a fast CO2 car you must do the following:
-Make the car light as possible
-Make the car have the smallest length possible
-Make it skinny
-Sand it down to make it have a smooth ride

Since I finished up shaping and sanding down my CO2 car, I worked with a software called Scratch (produced by the Massachusetts Institute of Technology (MIT)).
