What does a horizontal line on a position-time graph indicate about the object?
The object has a constant, nonzero velocity.
The object has a constant, nonzero velocity.
The object is accelerating.
The object is accelerating.
The object has a position of zero.
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's position is not changing over time. Therefore, the object is not moving and has a constant position.
A horizontal line on a position-time graph indicates that the object has a constant velocity. To understand how this works, here's what you need to know:
A position-time graph shows how the position of an object changes over time. The horizontal axis represents time, and the vertical axis represents the position of the object.
When a line on the graph is horizontal, it means that the position of the object remains constant over time. This means that the object is not changing its position at all. In other words, it is not moving.
Since the object is not moving, it does not have any velocity. Velocity is a vector quantity that includes both the speed and the direction of motion. When the position-time graph shows a horizontal line, the object has neither of these, so its velocity is zero.
Therefore, among the options you provided, the correct answer is:
"The object remains still."
The correct answer is:
The object has a constant, nonzero velocity.
A horizontal line on a position-time graph indicates that the object is moving with a constant velocity. This means that its position is changing at a constant rate over time. The fact that the line is horizontal suggests that the velocity is not changing, and therefore the object is moving at a constant speed.
