So then we get the magnitude of the acceleration vector, which I'm just going to call a sub c, is going to be equal to you could say the magnitude of this negative omega-squared but when you take the magnitude, it's like taking the absolute value in fact, absolute value is just the one-dimensional version of magnitude, that's just going to be positive omega-squared we don't care about the direction, sign gives us the direction, we just care about the actual size.
