Friction and curves

  1. Feb 7, 2012 #1
    1. The problem statement, all variables and given/known data

    If a car goes around a curve, which direction is its friction? Pointed towards the circle or outwards? Explain please. Thanks in advance.

    2. Relevant equations



    3. The attempt at a solution

    That depends. Think about what happens when the friction is pointed inward in relation to the car's maximum and minimum velocities. Which way would the friction point if the car is moving at a maximum speed? At a minimum speed?
