I think we can't have a negative displacement. Is that right?
Acceleration: the change in displacement / change in time squared
Since displacement can't be negative, and time can't be negative, acceleration also can't be negative.
But I know (it's in the books) that when we have decreasing acceleration, it's negative. How is that?
