TRUE and FALSE

Newton's third law can be written

Fab = - Fba

where Fab is the force body a exerts on body b, and Fba is the force body b exerts on body a. Statement (13) actually involves THREE bodies: the BALL, the PLAYER/PADDLE, and the TABLE. If we label them B, P and T in that order, then (13) implies that FPB = - FTB , which is not true. Newton's third law tells us only that

FBP = - FPB            and            FBT = - FTB.
