Each time the man stopped and took a break, the line on the Position-Time Graph (Blue Graph) would become horizontal (i.e., it would have zero slope). This is because when the man stops and takes a break, his position remains constant over time, leading to a flat line on the graph.
In the Position-Time Graph, the slope of the line represents the velocity or speed of an object. A positive slope indicates motion in the positive direction, a negative slope indicates motion in the negative direction, and a horizontal line indicates no motion (zero velocity).
When the man stops and takes a break, he is not moving. His position does not change during that time, meaning he is at rest. Therefore, the line on the graph becomes horizontal to represent this lack of movement.
Each time the man stopped and took a break, what happened to the line on the Position-Time Graph (Blue Graph). Explain why.
