Question

on a position vs. time graph, which feature would represent motion in the negative direction over time? (1 point)

an upward - sloping line segment
a downward - sloping line segment
a horizontal line segment
a vertical line segment

Explanation:

On a position - time graph, the slope represents velocity. Negative velocity means motion in the negative direction. A downward - sloping line segment has a negative slope, indicating decreasing position over time (motion in the negative direction). An upward - sloping line segment has positive slope (motion in positive direction), a horizontal line segment has zero slope (no motion), and a vertical line segment is not physically possible as it implies infinite velocity.

Answer:

a downward - sloping line segment
