Okay. What is it? Does it have a meaning? If it does, its meaning is
not coming from observations. Then, where does it come from?
No. ma is not an abbreviation for mR/T^2. F is not an abbreviation
for ma.
So why does it cancel? It's not a placeholder. It's not a temporary
variable. It's not a label. It's supposed to be a "physical" quantity
but it cancels out of formulas.
You might disagree with Newtonian mechanics;
No. I neither disagree or agree with Newtonian mechanics. To me,
Newtonian mechanics is a meaningless generalization. I'm questioning
one expression: F=ma. I cannot understand the types of the symbols in
this expression.
Another example: Physicists call this expression a=v^2/R an
"equation." To me this is not an equation, it is an identity: a= aR/R.
you should at least form a correct understanding of what it is that you are
disagreeing with.
I think this is what I've been trying to do but regarding F=ma, not
Newtonian mechanics.
In contrast, "GWB" *is* an abbreviation of "George W. Bush."
Okay. F is an abbreviation for Force. Force is an abbreviation for
that occult quality that emanates from the sun and travels the earth-
sun distance at zero second by breaking all of the conservation laws
of physics and then sets the earth in motion by instantaneously
communicating with the earth's center about how much of itself to
apply and then keeps the earth in orbit. . . It does all those
fantastic things at no time at all but this force cannot be found in
the formulas we use to compute the orbit of the earth. To me if a
quantity does not exist in formulas then it does not govern orbits.
M is an abbreviation for mass of the earth. Whatever the mass of the
earth is it has no relevance in orbit calculations because mass too
cancels out. Two out of three terms of F=ma cancel out of the
formulas. We are left with acceleration a. No. That's a goner too.
Because acceleration a stands for R/T2. R and T are the only two
quantities necessary and sufficient to compute orbits.
Each and every term of the fundamental equation of physics cancel out
of the formulas to compute orbits. Why did physicists write three
terms that cancel and made the cancelling terms the cornerstone of
physics? What am I missing here?
