To interpret a time graph (typically a distance vs. time graph):
- An upward-sloping line segment indicates that the object is moving away from the starting point, and the steeper the slope, the faster the object is moving.
- A downward-sloping line segment indicates that the object is moving back toward the starting point, and the steeper the slope in this case would also indicate a faster return to the starting point.
Based on this understanding, the correct response from your options is:
upward-sloping line segment: The steeper the slope, the faster the motion. downward-sloping line segment: The steeper the slope, the faster the motion.
