32-9 Relativistic Momentum and Mass (P749-751) In classical mechanics, the law of conservation of momentum (P=constant) holds in different inertial reference frames. But in relativity, if we continue to define P=mv, and m is a constant, the total momentun is not conserved for different inertial frames
Special case: [(P)] is rational: In this solution formula we can carry out the indicated integrations in literal form in the case in which [(P)] is rational. In our work, we deal in practical way only with rational,sn, and, so this function will be rational if D(p)is rational This will be true of every desired operation except predictor. Thus except in the case of prediction, the above
