Direction of friction in circular motion

[QUOTE="Vatsal Goyal, post: 6043108, member: 638196"] [h2]Homework Statement [/h2] I can't understand why friction acts radially inwards when a body is rotating on a rough turntable. If the friction is removed, the body would move tangentially, hence it has slipping tendency tangential, not radially outwards, then shouldn't friction act tangentially? [h2]Homework Equations[/h2][h2]The Attempt at a Solution[/h2] The idea that friction acts radially inwards seems very counter-intuitive to me. I know that there has to be a centripetal force as the body is in circular motion, and a force is required to balance the centrifugal force, but why is it friction and why wouldn't it act tangentially bugs me.
