A straight line going up or down on a position-time graph indicates a constant velocity of the object being represented.
- If the line is sloping upwards (positive slope), it indicates that the object is moving away from the starting point in the positive direction at a constant speed. This means that as time increases, the position of the object increases at a constant rate.
- If the line is sloping downwards (negative slope), it indicates that the object is moving toward the starting point (or in the negative direction) at a constant speed. In this case, as time increases, the position of the object decreases at a constant rate.
In both scenarios, the slope of the line corresponds to the object's velocity: a steeper slope signifies a higher speed, while a shallower slope indicates a lower speed. If the line is horizontal (zero slope), it signifies that the object is at rest (position remains constant over time).
