Friction in the Direction of Motion

  1. Nov 25, 2007 #1
    1. The problem statement, all variables and given/known data
    Is it possible for friction to act in the same direction as the motion of an object? If so, are there any real world examples? Thank you!

    3. The attempt at a solution
    I don't know where to start...

    I don't think there is....at least to my knowledge....friction always opposes motion...

    Place a box on a moving conveyor belt. What happens?

    (A better way to describe friction is to say that it always opposes slipping between surfaces.)
