When the man stopped and took a break, the line on the Velocity-Time Graph (Red graph) dropped, indicating that the velocity of the man decreased during those breaks.
This happens because velocity is defined as the rate of change of displacement with respect to time, meaning it measures how fast an object is moving and in which direction. When the man stops and takes a break, his motion is halted, and hence his velocity becomes zero because there is no change in his displacement during that time. As a result, the line on the Velocity-Time Graph drops to zero or near-zero during the breaks.
Each time the man stopped and took a break, what happened to the line on the Velocity-Time Graph (Red Graph). Explain why.
