Question

which of the following best describes an object moving forward on a position vs. time graph? the line has a positive slope the line is horizontal the line has a negative slope the line is curved downward

Explanation:

In a position - vs - time graph, the slope represents velocity. When an object is moving forward, its position is increasing with time. A positive - slope line on a position - vs - time graph indicates that the position of the object is increasing as time progresses, which means the object is moving forward. A horizontal line means the object is at rest (no change in position with time), a negative - slope line means the object is moving backward (position is decreasing with time), and a curved - downward line can represent a decreasing velocity while moving forward but not the best general description for moving forward.

Answer:

The line has a positive slope
