The Science of Speed
Research is one of the first steps in the engineering process. We posed the question "What makes a C02 car travel faster?" We brainstormed as a class and came up with these ideas: mass, aerodynamics, and friction. All of these factors may affect C02 cars, but "Which factor will affect the speed of the car the most?" Time to research! Use the resources below and come up with a hypothesis. You will apply what you learned to brainstorm ideas for the design shape of your car?
Mass
Newton's 2nd Law of Motion states: Acclerationon is produced when a force acts on a mass. This law provides us with the equation F = M x A. But what does that mean? How will it affect our car design? The video posted to the left may help to answer these questions.
Aerodynamics
Aerodynamics is the way air moves around things. Drag is an important aspect of aerodynamics that will affect your vehicle. Click on the image to the right to learn about drag.
Friction
Friction is the force generated when two objects come in contact with one another. Friction converts mechanical energy into heat energy. Basically, it will rob your car of speed and turn it into heat. Click on the image to the right to learn more about friction. Which parts of your car will come in contact with other surfaces?
