Newton's third law can be depicted by using few simple words- Every action there is equal to opposite reaction But these few words have the power to dominate our whole universe. Every interaction in our universe must obey newton's third law.
If we want to get more insight about Newton's third law, we can detach it into six particular statements. We have assumed that you have basic conception about the definition of force.
Action and reaction have same magnitude.
Action and reaction are opposite in direction.
Action and reaction work on two different bodies.
Action and reaction work simultaneously.
Action and reaction are same kind of forces.
6.Action and reaction work along a common straight line.
Explanation of 1st statement: If someone punches you in the face and you can't take revenge back, there is no cause to be disappointed. Because physics says, if he applies 100 N force on your face by punching, your face will give the same amount of force on his hand.
Explanation of 2nd statement: Force is a vector. If the gravitational force on apple due to the earth works along the negative 'Y' axis, the gravitational force on earth due to apple will work along positive 'Y' axis.
Explanation of 3rd statement: In our 2nd example of earth and apple system, action works on earth and reaction works on apple. There is no obligation to choose which one should be action and which one should be reaction between these two forces. You are free to choose it. We can also say that action works on apple and reaction works on earth. But the main theme is that action and reaction work on two different objects.
Explanation of 4th statement : If you turn away from pushing your car forward, your car will also finish to push you backward simultaneously. Action and reaction appear simultaneously and disappear simultaneously too.
Explanation of 5th statement: There are four fundamental forces in our universe. All interactions in our universe are nothing but these four fundamental forces. In our first example of punching or our third example of pushing car are the effect of electromagnetic force. Action and reaction of those two cases are electromagnetic force.
In our second example of apple and earth system, the action and reaction both are gravitational force. In universe, you will never find any event where action and reaction are two different form of forces. For instance, action is gravitational force and reaction is electromagnetic force. This will never happen.
Explanation of 6th statement : Action and reaction work along a common straight line. We know that action and reaction are opposite in direction. They are opposite vectors. It may happen that two vectors are opposite in direction on a same plane but don't lie on the same straight line. They can be just parallel with each other. But whenever we are talking about action and reaction case, these two forces work along a common straight line but opposite in direction.
there is no law of Einstein
