Question
Which type of motion is indicated by a position-time (x-t) graph that is a straight horizontal line parallel to the time axis?
Correct Answer
Option C is the correct answer.
Detailed Explanation
A horizontal line on a position-time graph means the position x is not changing as time t increases. Since the position remains constant, the object is not moving; it is at rest.
Hint
What does the vertical axis (position) value do as you move to the right along the time axis?
