Question

Use the graph to answer the question.

A velocity versus time line graph shows three lines. The vertical axis is labeled, velocity, and the horizontal axis is labeled, time. Line A moves to the right from a point on the vertical axis above the origin parallel to the horizontal axis. Line B slopes upward from the origin to the upper right corner. Line C moves to the right from a point on the vertical axis below the origin parallel to the horizontal axis.

Which quantity or quantities is/are increasing for the object represented by Line B?

(1 point)

velocity and acceleration

Answer 1

For the object represented by Line B on the velocity versus time graph, the analysis of the graph indicates that:

• Line B is sloping upward from the origin, which means that the velocity is increasing over time. Therefore, the velocity is increasing.
• Since the velocity is increasing from zero, the position of the object is also increasing. In physics, if the velocity of an object is increasing, it indicates that the object is moving away from the starting point.
• Acceleration refers to the rate of change of velocity. Since Line B represents a consistent increase in velocity over time (a straight upward slope), it indicates that the acceleration is constant and positive.

Based on this analysis, the correct choice is:

velocity, position, and acceleration.
