I was wondering if constant acceleration, for example, could just be written as $a_c$. I have seen it written that way, but I was not sure if it was legitimate. I did a quick search on Google but to no avail, so I turned to the best website out there.
I am new to physics, so having the knowledge of properly writing functions is a big deal. And if that is how you would denote constant acceleration the would just $a$ for acceleration mean that the acceleration is changing, as in a slope on a graph?
Sorry if this is confusing!
