I'm guessing you are confusing distance and position. If \(\displaystyle x(t)\) is the position of an object at time \(\displaystyle t\), then \(\displaystyle x(b) - x(a)\) is the change in position from time \(\displaystyle a\) to time \(\displaystyle b\). This may be negative or positive depending on whether the object is moving in a positive direction. \(\displaystyle x(b) - x(a)\) will be the distance traveled only if the object moved exclusively in the positive direction during that time. If the object ends up where it started, the change in position is \(\displaystyle 0\), but you probably wouldn't want to say the distance traveled was \(\displaystyle 0\).hi,
Just wondering if you can have a negative distance on a distance time graph (a negative sloping line)?
also can you find displacement on a distance time graph?
