interaction,

n according to Newton's law of interaction, the phenomenon in which every force is accompanied by an equal and opposite force. For every force there are two bodies–one to exert the force and one to receive it. Furthermore, whenever there is one force, another force must also be involved. If there is force to the right on one body, there is force to the left on another. Because the one force acts as long as the other, the impulses are equal. The total momentum of the two interacting bodies cannot change. Continuous interaction is demonstrated between the food that is masticated and the force applied to the food.
