Well for the most part my question is just that, what is the scalar for acceleration and if you would pleast explain?
It is the magnitude of the acceleration vector, if I understand your question correctly. Could you explain the nature of your difficulty further?
There’s at least two things that the OP might mean. First, there’s the magnitude of the acceleration vector, as Jabba said. So far as I know, this doesn’t have any particular name beyond “magnitude of acceleration”. There’s also a scalar quantity called the “pickup”, which is defined as the derivative of speed (speed being the scalar magnitude of the velocity vector). But this is hardly ever used; I’m not sure why it even has a name (beyond silliness for silliness’s sake, that is).
