Action-reaction-resultant Card C00151

RBF DEFINITIONS
Action-reaction-resultant:

Since "neither light not any other phenomenon is
instantaneous, then an action and the vector that it creates
is not instantaneous. Therefore the terminal end of an
action's vector occurs later. Therefore every action must
have a reaction at its starting end and a resultant at its
terminal end."					(Adapted.)
