Question

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





Line graph of velocity versus time. The X-axis is time in seconds, and the Y-axis is velocity in m/s. The graph has 3 segments: 1st, 2nd, and 3rd.
Which statement fairly compares segment 2 and segment 3?

Segments 2 and 3 have equal periods of time but the force during segment 2 is different than the force during segment 3.

Segments 2 and 3 have different periods of time, but the force acting in each segment is the same during each period of time.

Answer 1

Segments 2 and 3 have equal periods of time but the force during segment 2 is different than the force during segment 3.

Reason: acceleration is the slope of a v–t graph. Segment 2 is flat (zero slope → zero acceleration → no net force), while segment 3 has a nonzero slope (nonzero acceleration → a net force).
