Question

newtons third law of motion states that for every action there is an equal and opposite reaction, as shown in the illustration. which is another characteristic of these forces?
oa action and reaction forces always come in pairs.
ob action and reaction forces act on the same object.
oc action and reaction forces do not act simultaneously.
od action and reaction forces are greater for the object with the greater mass.

Explanation:

According to Newton's Third Law of Motion, action - reaction forces always come in pairs. They act on different objects (so option B is wrong), act simultaneously (so option C is wrong), and are equal in magnitude (so option D is wrong).

Answer:

A. Action and reaction forces always come in pairs.
