Relative Motion - 1D (disp) Reference frames are related to each other. Physics described must be the same, no matter which frame you use. X BA - position of B relative to A X PB - position of P relative to B X PA - position of P relative to A x PA = x PB + x BA Notice order of subscripts inner ones the same outer ones (on right) match left side
