| Jan 1, 2016 at 20:22 | comment | added | Gert | @user5539357: from a rotational POV, the normal force provides the centripetal force, while $mg\sin\theta$ provides the decelerating force. | |
| Jan 1, 2016 at 19:52 | comment | added | user5539357 | @Gert yes, I'm aware of that in only happens in the bend. What about my answers, do they make any sense? | |
| Jan 1, 2016 at 19:38 | comment | added | Gert | Note that vertical upward acceleration only takes place in the bend, that's why it didn't show up in my answer. What happens in the bend can be shown by considering it a rotation but not w/o calculus. | |

| Jan 1, 2016 at 18:17 | comment | added | user5539357 | 1. The normal force becomes $mg \cos\alpha$ ($\alpha$ is the slope angle). 2. Again, $mg \cos\alpha$. 3. It will increase, just like in the case when the ball was going in the opposite direction, up the slope. Technically, is it caused by the centrifugal force? (centrifugal force appears in non-inertial frame reference, and the frame reference here would be a piece of slope with the ball). | |
