Determine when a particle's speed is increasing from a graph

The video tutorial explains the concept of a velocity graph, focusing on the interval between 4:00 and 5:00 where velocity is positive and acceleration is negative. It discusses how to mathematically represent these concepts and the relationship between speed and acceleration. The tutorial concludes with the importance of writing these observations formally.
