Hi guys, I'm confused why friction is able to cause centripetal acceleration on a car that is turning in a circular road. Firstly, I think the radial acceleration is provided by the engine alone, and at any point of time the car velocity is tangential to the circular path, and friction is only directly opposing the linear velocity of the car tangentially, and not at right angles to the linear velocity. By the way, the road is totally flat. Shouldn't this be the sole role of friction here? How does it cause centripetal acceleration then? Thanks a lot!
