What does a horizontal line on a position-time graph indicate about the object?

The object has a constant, nonzero velocity.

The object is accelerating.

The object has a position of zero.

The object remains still.

The correct answer is: The object remains still.

A horizontal line on a position-time graph indicates that the object is not changing its position over time, which means it is not moving. Therefore, the object remains still.

The correct answer is:

The object remains still.

A horizontal line on a position-time graph indicates that the object's position is not changing over time, which means the object is stationary or not moving.

A horizontal line on a position-time graph indicates that the object has a constant position over time. In other words, its position does not change with time. This means that the object is not moving and remains still at a particular position. Therefore, the correct answer is "The object remains still." To determine this, we need to analyze the position-time graph and observe whether the line is horizontal or not.
