Question

Each time the man stopped and took a break, what happened to the line on the Position-Time Graph (Blue Graph). Explain why.

Answer 1

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.
