Is there a reaction force for a reaction force? According to Newton's third law of motion, for every action there an equal and opposite reaction.
If an object A applies a force (action) on an object B, object B applies an equal and opposite force (reaction) on object A. If we consider this reaction force as the action force applied by object B on object A, shouldn't there be a reaction force for every reaction force and hence infinite reaction forces?
 A: Forces come in pairs.  You could start at either object and then find the reaction force (force from the other object) from there, or vice versa.
The force of an object hitting the ground does not cause the ground to exert a force on the object... no more than the ground causes the ball to exert a force on it.  "Reaction" force is somewhat deceiving, since one force does not cause the other to react to it - they both come into play simultaneously.
Newton himself realized this.  His third law didn't mean that one force is a "response" force - it was just a way of saying that one force is never alone, it always has an equal and opposite twin.
A: The problem is the misleading term reaction. This implies that force A (the action) exists before its paired force B (the reaction), and causes force B to come into existence in response to applied force A.
This is wrong. Forces are always created in pairs, acting on different bodies. These paired forces describe the separate halves of an interaction between the two bodies. 
When object A collides with object B, it transfers momentum to B but it does not transfer force. A has momentum before it comes into contact with B, but the force which A exerts on B does not exist until the balls come into contact. The paired forces always come into existence at the same time and cease to exist at the same time. At every instant they are always equal and opposite; they are simultaneously the cause and effect of each other.
A: 1)Forces are currents and momentum is the charge. This brave electrical analogy has the value that establishes the notion of a circuit. You must find what closes the path of the forces. If I push you,that means you also push me and the earth underneath closes the circuit.
2)Why you read simultaneity at the comments and you don't protest?
That means interactions are faster than sound, not to say faster than light.
