physics 2

a mutual action between objects where each objects exerts simultaneously an equal-in-magnitude and opposite-in-direction force on the other

the force that is equal in strength and opposite in direction to the reaction force

the source of a force

a push or pull that acts on an object because of an interaction between the object and its environment

all forces come in pairs, called interaction pairs. the two forces occur simultaneously; each force acts on a different object; each force is equal in magnitude but opposite in direction

the object or collection of objects upon which forces act

the force that is equal in strength and opposite in direction to the action force
