Can anyone explain the above concept in a concise manner? I am proposing that banking aids motion at maximum speed on a curved surface. I am not totally sure how to include the role of side friction and centripetal force. Any further suggestions would be appreciated.
Another question relates to why at a certain speed a car experiences no sideways frictional force in a plane parrallel to the road surface. I am proposing that sideways friction induces circular motion in a car on a straight road. Since the plane is parallel to the road surface, the motion has to be linear. I am not sure how it relates to a certain speed.
Any suggestions? Thanks!
