Does mass effect the distance of objects rolling down a slope? - Answers

If you are in a real world situation there are a lot of factors to consider. In theoretical situation, ignoring friction and air drag etc, if a roller with mass m rolls down a slope to a horizontal surface it will continue rolling on the horizontal surface indefinitely. The velocity attained will be affected by the distribution of mass in the roller. If most of the mass is concentrated to a small volume that is axially located then the velocity will be different from if the mass is concentrated to the outer perimeter of the roller. In the latter case of peripheral mass concentration the acceleration will be slower but more energy will be stored as rotational inertia and in a real world situation the roller will continue rolling further.
