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

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?

Answer 1

To determine during which time segment the object is moving forward but slowing down, we can analyze the velocity vs time graph in terms of the sign of the velocity and its change over time:

• A: The velocity is positive, and the line is horizontal, meaning the object is moving forward at a constant speed. It is not slowing down.

• B: The velocity is positive, but the line is sloping downward towards the horizontal axis, indicating that the object's speed is decreasing. Thus, the object is moving forward but slowing down.

• C: The velocity is zero at the horizontal axis; the object is momentarily at rest.

• D: The velocity is negative, meaning the object is moving backward.

• E: The velocity is zero, which means the object is also at rest.

Based on this analysis, the correct response is:

B
