Question

Use the graph of velocity vs. time for an object to answer the question.

An illustration shows the velocity versus time graph. The vertical axis of the graph is labeled negative at the bottom and positive at the top. A line parallel to the horizontal axis from a point on the vertical axis near the top is labeled, A. The line then slopes downward passing through the horizontal axis at point C. The part of above C is labeled B and the part below C is labeled D. The line then becomes parallel the horizontal axis. This part of the graph is labeled, E.

During which of the labeled time segments is the object moving forward but slowing down?

To determine during which time segment the object is moving forward but slowing down, we need to analyze the velocity vs. time graph.

  • Moving forward means that the velocity is positive (above the horizontal axis).
  • Slowing down means that the object’s velocity is decreasing over time. On a velocity vs. time graph, this is indicated by a downward slope (the line is decreasing).

Now let's evaluate the labeled segments:

  • Segment A: The velocity is positive and constant, so the object is moving forward but not slowing down.
  • Segment B: The line is positive but is also decreasing, indicating that the object is moving forward but slowing down.
  • Segment C: This is where the velocity crosses from positive to negative, so the object is transitioning from moving forward to moving backward.
  • Segment D: The velocity is negative, so the object is moving backward.
  • Segment E: The velocity is constant (parallel to the horizontal axis), meaning the object is not accelerating or decelerating and is not in motion.

From this analysis, the correct answer would be:

B

This is the segment where the object is moving forward (positive velocity) but is slowing down (decreasing velocity).
