Homework Statement
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?
Homework Equations
The Attempt at a Solution
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.
