Abstract: 2 psychological principles in the perception of collisions were tested on 25 men students. According to the principle of momentum, when 2 objects, A and B, collide, B stationary before and A stationary after impact, if the ratio of their momenta (M-sub(A)V-sub(A)/M-sub(B)V-sub(B)) is unity, Subjects will report that A alone produced B's movement (launching); if less than 1, that A triggered B's movement (releasing); if greater than 1, that A launched B but that B's further movement was impeded by an additional force (braking). Somewhat similar expectations were deduced in terms of the ratio of kinetic energies. Both principles were supported by the data obtained. From Psyc Abstracts 36:01:3BC94N.
