Skateboarding Frame of Reference Demonstration

The video tutorial explains how velocity measurements depend on the observer's frame of reference. It illustrates this concept with examples, such as a skateboarder tossing a ball, showing how different observers perceive the motion differently. The tutorial emphasizes that all motion is relative to the observer's viewpoint. It concludes with a promise of another example involving a ball dropped from a moving car.
