# Do every action has an equal and opposite reaction?

I don't think so

e.g. if we slap on our servant's face, for sure he is not gonna slap us back

prove it wrong with some other good examples

Relevance

Every action has an equal and opposite reaction due to the Law of Conservation of Motion.

Although your servant's "reaction" may vary..When you slap him, you exert a certain amount of momentum on his face with your hand. His face must push back with the same amount of force..Or else your hand would go completely through his face.

No. That is Newton's 3rd law of motion, and applies solely to classical mechanics. There is no logical connection whatsoever between that the idea of the future being predictable. The way you should be arguing is this - physics shows us that we can describe what happens in the universe entirely in terms of mathematics. Every calculation gives definite results, they always work, and so it is reasonable to elevate those equations to the status of unbreakable laws - we have no reason to think that they aren't. Therefore if we knew all the variables, we could confidently calculate the future. Where this falls down is that chaos theory is giving us suggestions that this isn't always the case, and quantum physics shows that on a small scale, the universe is not predictable - the equations are in terms of probability, not exactness.

As material world action is concerned, yes.

If you slap your servant's fact, his face is going to react with the same force but in the opposite direction applied to your hand.

But you won't feel it as if your hand is being hit by some one.

The reaction is not given by slapping but by rejecting the job and then you will suffer without a servant...

You are talking about human behavior but the theory for scientific result. So far as human behavior is concerned, slap on your Dad's face and wait to see the result.

Yes!!!

The amount of force u apply to ur servants face sure as anythings gonna be the amount it hurts him!

Prove me wrong ... ;)

No man, if you slap your servant's face he won't smack you back...but he will get back at you by spitting in your food. That's Newton's Third Law at it's finest.
