Hey i have a doubt . i have not tried this experiment but i wanted to know what would happen. If we take a tube bending at the end and joining to a 5 km long pipe which is frictionless (assume) and there is no air to offer air resistance . So when i start rolling the ball will it stop or not . You might tell no but please take into consideration about the ball hitting the surface and producing a sound and hence losing energy.Even if the fiction is not hitting the object , the object should also be hitting the surface ( Every Force has equal an opposite reaction) . Please tell with reasons
