Question

how can we say that Newton's laws are correct ?? ​

Answer 1

Answer:

Newton's Laws" are - like most physics - a mathematical model that describes how the world - or the universe - works.

Explanation:

All models are wrong, in that they don't describe the complete complexity of the physical world, but some models are useful, in that they let us make predictions.

Newton's Laws, as a model, work well, unless you are dealing with things that have very large mass, move at a significant fraction of the speed of light, or are very small in size. At that point, things like relativity, and the uncertainty principal become significant.

Newtons' Laws also don't work very well in isolation when you consider things like air resistance or friction, for example.
