a Newton's law states that : F=m.a , but I realize that it belongs to our sense , but may be someone know more about this . if you have any explaination or proof , let me know :)

Forget about Newton's laws. Think about how you "prove" anything in science!
There is no such thing as "proof" as rigorous as that in mathematics, i.e. a logical proof. There are such a thing as "valid" evidence! The fact that your house still stands is an evidence for the validity of Newton's laws. The fact that we can actually map and predict the location of celestical bodies (i.e. we shoot a space capsule here on earth, and months and years later, actually reach a planet that wasn't at that location months and years earlier) is another evidence for the validity of Newton's laws.

Can you measure force? Well, if you can measure mass and if you can measure the acceleration then you can measure the force. Otherwise I don’t think you can.
