Momentum conservation in collisions

  1. Oct 12, 2009 #1
    can the percentage error for final total momentum be negative in an elastic collision? It doesn't have absolute value in the equation given and I get a negative number, p(final) - p(initial)/p(initial) x 100 though small -0.528

    Hi ba726, welcome to PF. Yes, errors can be negative.
