Position Vectors and Distance between Two Points

The video tutorial covers position vector notation, explaining unit vectors I and J for horizontal and vertical movements. It introduces the concept of using an origin as a reference point for position vectors and demonstrates how to calculate the distance between two points using vector notation. An example involving ships is used to illustrate the calculation process, including the use of Pythagoras's theorem to find the magnitude of the vector. The tutorial concludes with a summary of the key concepts and encourages students to apply these in their assessments.
