Our class is designing a Co2 car
The key to building faster CO2 cars is to focus on the design factors that increase acceleration. Let's review Newton's Second Law of Motion.
Frontal area is what the air stream sees or what you see looking at the front of a car. As you would expect, the larger the area the greater the drag because of the increase in frontal pressure. Drag force is proportional to area so if frontal area doubles drag force doubles. Keeping frontal area to a minimum will reduce drag.
newtons second law The acceleration of an object of constant mass is proportional to the force acting upon it.
these are the refinements i made to my car
