Physics

In a position-time graph, the slope of the line represents the velocity of the object. If the slope is positive, it indicates that the object is moving in the positive direction. If the slope is positive, it indicates that the object is moving in the negative direction.

Analyze each time - interval:

0 - 10s:

Since the slope is positive, the object is moving in the positive direction during the 0 - 10 s time interval.

10 - 15s:
