Absolutely. It's not 'true'. It's an extremly good approximation on a macroscopic scale and so long as your speeds are relatively low, but that's all it is. I've answered that by way of clarifying my statement. Anymore discussion would definitely be tipping into debating.
We are not debating, we are discussing, if we are debating, then there would be an issue of me trying to prove you wrong, or vice versa. This is not the case, this is an open share of information, where we are seeking to educate each other, if education on an open platform is debating, then everything is debating.
As to answer your question, when you say "slow speeds" (which is very misleading in it's own right, just to let you know) you do realize that the F=MA is applied, up until the speed of light, after the speed of light, and only AFTER the speed of light has been reached or exceeded, does a different Law apply, however this different law does not apply to speed slower then the speed of light. This is also something you have put fort that is misleading, the Different laws of Motion, as they stand, are not interchangeable, the Rules change after the speed of light has been reached, this does not make either of them "Approximation's" in any way shape or form. It just means that the "rules change".
Funny thing there with Physics, when the rules change, they change on a complete level.
As such, the Law of Motion, F-MA is applied to any and all matter that is moving slower then the speed of light,
Now, Quantum Physics, which deals with the movements of atomic particles move faster then the speed of light, as such, they apply a different (completely different) rule set to them. Hence why it is a different field of Physics. Just as complete Voids and Pure mass have different laws and rules applied them. But the Laws that apply to the Situation, Apply in Whole, not part. And the different laws can not cross the boundaries of their applied field and situation.
As such, this is not approximation, it is that the Laws of Physics change, by scale. What works on one scale, does not work on all scales.
However, when a Theory, and a Law collide, the Law always wins.
The law on the scale that it applies to, can not be broken, if it is broken, then the law is not applied, and removed, and a new law needs to take it's place, or no Law shall exist on that scale for that situation.
Allow me to explain, Galileo's law of Motion F=MV, we incorrect, it looked correct from a limited view , but did not fully apply, hence, the law was replaced by Newtons law of Motion, F=MA, all equations made from or worked from F=MV would then need to be re-worked as they were applied under a false or incorrect Law, and would need to be corrected under the proper and correct law.
Now, the Laws applied to Quantum Physics do not apply to Larger Scale physics, IE: The Laws of Atomics do not apply to the behavior of mass in a macro scale, as such, both Laws are correct, and accurate, and neither is breakable.
This becomes a difficult aspect of Laws for people to grasp, and in the end, it also becomes a difficult concept for people to apply.
This is a common trick or tactic for many supporters of Evolution to try and say that a Theory can overcome a Law, but such can not be true, The Law must support the Theory, or the Theory by default becomes moot. a Theory, can not, under any circumstances, disprove a Law.
Only Evidence can prove or disprove a Law.
And, a Theory, is not Evidence.
I hope I have explained this to you in clear detail.
God Bless
