What does a horizontal line on a position-time graph indicate about the object? (1 point ) The object has a position of zero. The object has a constant, nonzero velocity. The object is accelerating. The object remains still.
The correct answer is "The object remains still."
A horizontal line on a position-time graph indicates that the object has a constant position over time. This means that the object remains still and has a position of zero.
A horizontal line on a position-time graph indicates that the object has a constant velocity. To understand why, we need to analyze the relationship between position and time.
On a position-time graph, the position of an object is plotted on the vertical axis (y-axis) and time is plotted on the horizontal axis (x-axis). By observing the slope of the line on the graph, we can determine the object's velocity.
If the line is horizontal (with a slope of zero), it means that there is no change in position with respect to time. In other words, the object is not moving. Therefore, the correct answer is that the object remains still.
