What do you mean by that? Mathematical models proves that Newton's laws must be true? — TheMadFool
The OP is not as concerned with the meaning of "proof" as he is concerned about the circularity of the proof. — TheMadFool
Every object in a state of uniform motion will remain in that state of motion unless an external force acts on it.
How can you prove Newton's laws? — Fernando Rios
Newton's laws being theorems from other assumptions doesn't mean they describe reality.

Unfortunately, you cannot prove anything about the real, physical world, simply, because its construction logic is unknown. The term "proving" means that you demonstrate that a theorem necessarily follows from the construction logic of its world. — alcontali
I would like to know how can you prove these laws, but not using devices that use the the same laws. — Fernando Rios
Does someone just know what were the experiments Newton performed to prove his laws? — Fernando Rios
Sorry if I seem ignorant, but how can we know they are true then? — Fernando Rios
Thank you for your answer. What are the experiments that Newton used to show their laws are true? — Fernando Rios
I just see the example shown by a drawing. What variables are being measured there? How are they measured? — Fernando Rios
That circularity is gestured at as if it existed, but where and how exactly does it exist? — tim wood
There's an even bigger point here which the OP is hinting at - that the theory of relativity which has supplanted Newton's was proven by instruments that had to follow Newton's laws. — TheMadFool
If you've read my other posts then you know that the Theory of Relativity was derived from measurements from instruments that followed Newtonian laws. What do you have to say about that? — TheMadFool
Every child who asks "Why?" sometimes gets caught in the whys and keeps asking long after the efficacy of the question has been exhausted. — tim wood

The problem for the OP is how an instrument that is Newtonian can ever prove that some other event is NOT Newtonian in nature. — TheMadFool

So many respondents missing the point regarding "proof". He clarified that by "proof", he means showing to be true. — S
