Considering gravity as a force completely destroys Newton’s 2nd Law. A force needs to be cause by something, so what would it be?
Considering gravity as an effect only makes the most sense to me for now.
I think it semantics on how this stuff is defined. This is why I asked the questions that I did.
If we consider gravity as a force, then what happens to Newton’s 1st and 2nd Laws? They fall apart. Plus something would still have to cause this force.
This is what messed me up.
F = ma — (I’m cool with)
a = F/m — (I’m cool with)
m = F/a — (makes no sense whatsoever)
How can two things that are results of something create a mass? That is where quantum comes in and I’m not really that deep into that.
The only way I can see gravity is it being an effect from mass. This would allow Newton’s second law to hold and supports Einstein’s theory.
But even Einstein’s theory has the same issue
E = mc^2 — I’m cool with
m = E/(c^2) — makes no sense
So we keep circling around with “what force or energy causing the creation of mass?” This is quantum level stuff we have reached.
This has always been my issue with physics. In a pure mathematical world we can not get away with half the stuff that physics get away with. We are not allowed to assume.
I think so, but I have a tendency to question further on stuff.
But it also reminds me how much we don’t know in physics and how we do have to make assumptions in some areas to make things work.
I’ll tell you what, this whole discussion got me looking at Newton’s Laws a lot differently.
Actually got me looking at a lot of things differently, especially as I think about how these emperical physical constants are used.
