Learn how to find when a particle is changing direction from a velocity graph

The video tutorial explains how a particle's velocity changes at specific times, T=4 and T=8. At T=4, the velocity changes from positive to negative, indicating a change in direction from right to left. At T=8, the velocity changes from negative to positive, showing a change in direction from left to right. These changes in direction are crucial for understanding the particle's movement, and the video emphasizes the importance of recognizing these changes by observing a graph.
