= P^; it is a work-ing force for the body of mass M, but a resistance for M,hence the separate symbols for the numerically equal forces(action and reaction). Similarly, the friction at JL is jSj = /*,; a resistance for M,a working-force for M. (la some cases, of course, frictionmay be a resistance… … FlQ. 1B6. Fio. 157. Fio. 155. dicular to AA. In Figs. 156 and 157 we see M and Mfree, and their corresponding small rotations indicated. Duringthese motions the kinetic energy (K. E.) of each mass haschanged by amounts d(K. E.)m and d{K.
