Since I am an amature at mathematics can some one answer the following questions? Is the term g ,in the rolling resistance equation essentially one, on the on the surface of earth. With minor variations due to elevation that are small enough to be ignored for fuel economy purposes? Is wind resistance an exponental equation due to the v squared term and the rolling resistance equation linear with constant slope due to v or no other them being squared? Feel free to be wordy with your answer I welcome details. A suggested conclusion to the wiki being like the introduction that understanding the forces acting on your car you can be a more efficent driver and modifications to your car more effective.
