The discussion revolves around the factors that cause a car to skid while traveling on a circular track with kinetic friction. Participants explore the relationship between centripetal force and friction in the context of circular motion.
The discussion is ongoing, with participants sharing insights about the forces at play in a level unbanked curve. Some guidance has been offered regarding the relationship between velocity and friction, but there is no explicit consensus on the final interpretation of the conditions for skidding.
There is a noted distinction between static and kinetic friction in the context of the problem, which may influence the understanding of the skidding condition. The discussion is framed around a general question rather than a specific homework problem.
the friction force is the centripetal force.Nishikino Maki said:That actually makes sense because on a level curve the friction and centripetal forces are the only ones pointing to the center.
yes, where u is the coefficient of static friction, not kinetic friction.Then I suppose it would be when the velocity of the car is greater than \sqrt{µgr}?
