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.

What does a positive velocity indicate about the direction of the particle's movement?

How can we determine when a particle is moving to the right or left?

Explain the significance of the particle moving from positive to negative velocity.

What does the change in direction of the particle imply about its motion?

At what times does the particle change direction according to the text?
