on a position vs. time graph, which feature would represent motion in the negative direction over time? (1 point)\n\nan upward - sloping line segment\na downward - sloping line segment\na horizontal line segment\na vertical line segment
Answer
Brief Explanations:
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
