Each time the man stopped and took a break, what happened to the line on the Velocity-Time Graph (Red Graph). Explain why.
(the graph continues in a straight line)
If the man stopped and took a break, the line on the Velocity-Time graph would become a horizontal line at zero velocity. This is because when an object is at rest, its velocity is zero. Therefore, there would be no change in the velocity of the man during the break, resulting in a straight, horizontal line on the graph.
When the man stops and takes a break, the line on the Velocity-Time graph (Red graph) remains constant and continues in a straight line. This is because the velocity of an object during the break is zero since the man is not moving. Therefore, there is no change in velocity over time, resulting in a flat line on the graph.
Based on the information provided, it seems like the red graph represents the velocity-time relationship for a man who stops and takes breaks during some period of time. When the man stops and takes a break, the line on the velocity-time graph would remain as a straight line, indicating a constant velocity of zero during that period.
To understand why the line remains straight, we need to recall the basic principles of velocity and time. Velocity is defined as the rate of change of position over time, and it indicates how fast an object is moving in a particular direction. In this case, the man is not moving during the breaks, so his velocity is zero.
On a velocity-time graph, time is represented on the x-axis, while velocity is represented on the y-axis. A straight line on the graph indicates a constant velocity. If the line stops at a certain point (as a vertical line), it means that the velocity is constant, but the time is not changing (i.e., the object is not moving).
Therefore, each time the man stops and takes a break, the line on the velocity-time graph would remain as a straight line at the zero velocity position, indicating that there is no change in velocity during those periods.
