Theory A brief description of the theory will now be given. First we will develop a formula neglecting air resistance and using a sliding frictionless particle on our incline with height h. Then we will improve the theory by discussing air resistance and rotational energy using a more realistic steel ball rolling down our incline. The point of the ramp in the above picture is that you have to gently convert the kinetic energy along the incline into pure horizontal motion as the ball is launched off the table. That is the secret of the
