Use the graph of an object’s velocity over time 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.

Which two values would likely be equal for the object during the times marked by segments B and E?

Answer 1

To analyze the graph and the segments mentioned:

• Segment B shows a downward slope from a higher positive velocity to a lower velocity until it crosses the horizontal axis at point C. This indicates that the object is decelerating (or accelerating in the negative direction).

• Segment E is where the velocity remains constant, indicating that there is no acceleration during this time period.

Given these observations:

• Velocity is different in segments B and E, as segment B has a negative slope (indicating changing velocity) and segment E has a constant velocity.

• Acceleration is non-zero in segment B (since the velocity is changing) and zero in segment E (since the velocity is constant).

• Net force would also be related to acceleration. There would likely be a net force acting on the object in segment B (due to acceleration) and likely no net force in segment E (due to zero acceleration).

• Mass would remain constant throughout the segments and does not change with velocity or acceleration.

Therefore, the two values that would likely be equal during segments B and E are mass, as mass does not change.

The answer is:

mass
