Friction question?

  1. Jul 22, 2009 #1
    Does the force of Friction acting on an object equal the applied force on an object if it is in constant motion?

    Is that one of Newton's Law's? Which?

    Thank you :smile:

    Newton's 2nd law tells you that if an object has constant velocity (thus zero acceleration), then the net force on it must be zero.
