As an end of the year easy grade, our physics teacher assigned us a 20 point project in where we design a lab and analyze the data in a power point. I chose to use an inclined plane and a roller cart. My idea was to analyze the effect of a sail (thus creating air resistance) on the acceleration of the cart. So, I had two identical carts, one with no sail, and another with a large piece of cardboard attached to it to create air resistance. I performed trials in which position and velocity were recorded for five seconds.
My questions are:
-How can I analyze air resistance with my method?
-What are useful equations that I can use?
-My teacher mentioned the cross sectional area of my sail; how is this related?
*Note: Screen shots of data coming soon.
