Velocity Time Graphs

This video tutorial explains the differences between speed and velocity, highlighting that speed is a scalar quantity with only magnitude, while velocity is a vector with both magnitude and direction. It demonstrates how to plot velocity-time graphs, using Alice's journey as an example to show acceleration and deceleration. The video includes an interactive exercise for viewers to practice drawing these graphs. It concludes with a fun fact about human running speeds and a brief mention of future topics.

What happens to Alice's velocity as she decelerates towards her destination?

What is the fastest running velocity of a human, and how does it compare to our ancient ancestors?
