The way I see it, the equation F=MA is just another example of how abstract "mathematical" symbols can easily become completely divorced from the essential concepts underlying them, which get forgotten.
People look at the "F" and often start looking at it as a "single," self-sufficient representation of something. They can forget that the "F" is not a simple, uncomplicated thing. because it looks so simple. It's just a simple "F," that's all, and it's so easy to manipulate mathematically that way. It can easily be seen, mathematically, that M is "simply" F/A, and that A is "simply" F/M.
To remind people of this, the equation should really be written as NET F=MA
Looked at from a different perspective, F=MA is just circular in character and is just a self-proving tautology.
