What happened to the line on the Position-Time Graph (Blue Graph) when the man returned to the 0 meters? Explain why
When the man returns to 0 meters on the position-time graph, the line representing his movement will intersect or touch the x-axis (time axis). This indicates that the man has completed his journey and returned to the starting point.
The reason why the line intersects or touches the x-axis is because at the starting point, the position of the man is 0 meters. This means that the man is not positioned ahead or behind the starting point; he has reached the original position. Therefore, on the position-time graph, the blue line representing his position will align with the x-axis at that specific time when he returns to 0 meters.
To determine what happened to the line on the position-time graph (blue graph) when the man returned to 0 meters, you need to understand how to interpret position-time graphs.
A position-time graph represents an object's position (or displacement) as a function of time. The horizontal axis represents time, and the vertical axis represents position. The line on the graph represents the object's motion over time.
When the man returned to 0 meters, it means he went back to the starting position or the point of reference. On a position-time graph, this corresponds to the point where the position value is zero on the vertical axis.
If the man returned to 0 meters and continued to remain stationary at that position, the line on the position-time graph would remain flat and horizontal at the zero position. In other words, the line would be straight and level at the zero mark on the graph.
However, if the man returned to 0 meters and then started moving in the opposite direction (either forwards or backwards), the line on the position-time graph would change accordingly. It would show a change in position over time as the man moves away from the zero position.
To summarize, if the man returned to 0 meters and remained stationary, the line on the position-time graph would be flat and horizontal at the zero mark. But if the man started moving again after reaching 0 meters, the line would change accordingly to reflect his new position.
When the man returned to the 0 meters on the position-time graph, the line representing his position would intersect and coincide with the x-axis (time axis). This means that the line representing the man's position will touch the x-axis at the point where he reached back to his starting position.
The position-time graph shows the relationship between an object's position and time. The x-axis represents time, while the y-axis represents position. When the man returned to the 0 meters, it means that his position in the graph is zero at that particular time. This is represented by the line touching the x-axis.
This happens because the position is measured relative to the starting point. When the man returns to the starting position, his position becomes zero since distance traveled is measured from the reference point. The line touching the x-axis indicates that the man has reached the starting point in the graph.
