The video tutorial explains the difference between average and instantaneous velocity using the example of a train journey. It highlights that average velocity provides information over a time interval, while instantaneous velocity gives the speed at a specific moment. The concept of instantaneous velocity is defined mathematically as the derivative of displacement with respect to time. The tutorial also demonstrates how to calculate instantaneous velocity graphically by finding the slope of the tangent to the position-time curve at a given point.
