Question

What does a horizontal line on a position-time graph indicate about the object? The object is accelerating. The object has a position of zero. The object has a constant, nonzero velocity. The object remains still.

Answer 1

A horizontal line on a position-time graph indicates that the object remains still. This is because the position of the object does not change over time; therefore, its velocity is zero. A horizontal line signifies that there is no movement from the object's initial position.
