Why newtons second law is fundamental law?

First of all, all 3 laws of Newton are fundamental. Maybe someone told you that 2nd law of motion is fundamental because many conservation laws can be derived from this second law. But this second law is formed from experimental observations. read more

In other words, you want to boil down the rules of mechanics down to the most basic, fundamental postulates/laws/assumptions and since you see that Newton's second law is the most fundamental, you want to rip the first law of its status as a fundamental law. read more

The second law is the one that tells you how to calculate the value of a force. Force (measured in Newtons) is one of the fundamental physical properties of a system and comes in many forms. read more
