Determine when a particle is moving down from a position graph

The video tutorial explains the concept of particle movement by focusing on position rather than path. It clarifies that a particle's position at different times is not its path. The tutorial discusses how negative velocity can be represented by a negative slope on a position graph, emphasizing the importance of using slope instead of velocity. It also covers how to interpret graphs to determine when a particle is moving down, specifically identifying intervals where this occurs.

Why is it important to avoid using the term 'velocity' when discussing the position graph?

Explain the significance of negative slopes in the context of the particle's motion.
