This Week in Physics

During this week in AP Physics C, we have begun our studies in Dynamics. At first it was not too bad... then came air resistance. It seems like a pretty simple concept but it is in fact not. I don't have much experience in Calculus yet, so the differential equations are still pretty difficult to understand. There is still a good amount of time before the test for me to study this concept so hopefully I will get a good grasp on it before the test. Other than the differential equations, the confusing part for me is why there are two equations for Fdrag which are Fdrag = bv and Fdrag = cv2 . Why do some circumstances use one equation and others use the other equation? Even though this concept is really difficult, I think it is extremely important for accurate calculations. In past physics courses we have always neglected air resistance but here on earth there is usually air all around.
