Are Newton´s asumptions really true?

However, wiht regards of the force from the floor (F), why doesn't it diminish and where is it's powersource?????????

This actually an interesting question... for people who actually want to learn Physics.

The answer is a scientific value called 'Work' (not to be confused with the non-scientific use of the word). Work is defined as "a force applied over a distance". Since the Force being put on you by the floor (which is counteracting the force on you from gravity so that you don't fall) isn't being applied over a distance, there is no Work and no "powersource" is needed.

I think I am wasting my time with Quehoniaomath... but if anyone is really curious, there is some interesting science here.

Here's an experiment for you that will quickly show you how the floor provides force. Walk across the roof of a 12 story building. Notice how you are held in place at that height. Now walk off the edge of the roof. Let us know your conclusions.

Nice one, but you don't answer my questions at all!

I think that this injunction from you is a waste of your energy. He's much worse than that. He's a pathological liar who is apparently unable to realize that he's not likely to pick up science mistakes that people all over the world have missed for centuries without even learning a smattering of the subject. He's made just about everyone who's read his posts hate him and seems to be fine with it, although no rational person would define that as success. I could have corrected his childish physics ideas here easily, but he's obviously not worth it. Dealing with him in any way is a waste of time, and, furthermore, it kind of seems as though he's enjoying the attention.

pathological liar.

Everyone can't know physics, any more than I know most professions that I haven't studied or worked in, but I am dumbfounded by the idea that anyone (not this guy, he's just a troll) would proclaim that he has disproven really basic physics used successfully and thought about by three centuries of scientists around the world without first taking even one class in it. I say "without taking even one class in it" because anyone who is confused by Newton's third law has certainly never passed a physics or mechanical engineering class.

used successfully and thought about by three centuries of scientist

It answered your question perfectly. Without the work of the floor or roof holding you up what happens? Did you do the experiment? Clearly the floor/roof is doing work otherwise you would fall through them. Gravity is applying the same force when you are on the roof as when you step off it

His proclamations are just that; proclamations. No math, nothing. (I expect he'll say that 2+2=5 and we are all fools for believing otherwise). This person is an attention troll.

Furthermore, questioning Newton or relativity or anything else does not mean one has not studied it offcourse.

The fact that you gave that ridiculous boat example without the slightest idea of how force works or the slightest clue of how to explain the theory proves that you have not studied Physics .

about the "subatomic particles" there is a lot wrong with them including Quantum Mechanics.

I don't think you actually believe all this **** you have been posting; I think you are just trying to spin this out as long as you can.
