According to Newton's third law of motion-how are action and reaction related to each other?

Answer 1

Newton third law is really self explanatory, however since you ask the question I will try and answer it for you. If you pushed against a wall with a force of say 2 kilos, then the wall would push in the apposite direction with the same amount of force. Even if the wall had a large mass much greater than yours the action and reaction would be the same. Going to the billiard ball example, when the cue ball strikes the other ball both will move off in equal but opposite directions. There can be a time when the cue ball will not move at all after it has struck the other ball. This happens when it hits the other ball dead center hard enough to transfers its energy to the other ball.

Answer 2

Newton's third law of motion states that for every action, there is an equal and opposite reaction. This means that whenever one object exerts a force on a second object, the second object exerts an equal force in the opposite direction on the first object. In other words, the action and reaction forces are always equal in magnitude and opposite in direction.

Answer 3

The sum of action A and re-action R is zero, A+ R=0. This is usually phrased as:

"for every action there is an equal and opposite reaction".
