Hi everyone Thanks for viewing this thread. Hope it's in the right forum. I have some questions on basic mechanics that could really do with some clarifications, so I'd really appreciate any help you could provide. 1. Consider a ball with sufficient initial speed such that it moves in a...

Sorry for the bump. But I gave this problem some further consideration and I'm just wondering how one would proceed with the problem if the ice dome were elliptical in shape with precisely defined semi-major and minor axes. Thanks

I agree. But suppose that we're dealing with more complex problems where the path of motion is less obvious, is there no way of finding the path since the magnitude of the normal force is unknown? And also, isn't the normal force greater than weight when a falling object rebounds from the...

I can accept that. But besides appealing to common sense to see that the body follows a circular path, is there any other way to account for why the normal force conveniently adopts the correct magnitude to maintain circular motion? I know that this magnitude is related to the compression of the...

Thanks for the reply. But what I don't quite understand is why the normal force takes whatever value it does at a particular angle. Why is it impossible for the normal force at a given angle to be so large that it counteracts much of the radial component of gravity and leaves a small net force...

Homework Statement Homework EquationsThe Attempt at a Solution I know that the solution involves setting the normal force to zero and equating the radial component of gravity to centripetal force. But why is it not possible for the normal force to decrease at a sufficiently low rate such...

So is the attempted motion of the contact patches parallel to the axis of the wheels due to the inertia of the car? I did find a diagram online but I'm not sure if it's correct or not. It may help with the explanation.

Thanks again. So in practice, the only way to deduce a value for normal force or tension is to simply observe the motion of the affected object? I just found one and am in the process of reading through it. I'll see if I understand it. I can see that this would give rise to a force...

Thanks for the quick reply. That's good to know. So do actual equations exist for these forces, albeit most likely being too complicated for me to understand? Could you please elaborate on this? But how are the contact patches attempting to move perpendicularly to the velocity of the car...

Hi everyone. Thanks for attempting the audacious challenge of deciphering the undistilled chaos that is this thread. I'd appreciate any efforts to clarify my very much flawed understanding of basic physics. 1. This is most likely a trivial question but why is the normal force perpendicular to...
