This video tutorial explains the intuition behind curvilinear motion, focusing on two coordinate systems: the familiar xy system and the nt system, which is useful for circular motion. The nt system simplifies equations and is advantageous for analyzing circular paths. The video covers the differences between these systems, how to apply them to motion analysis, and the benefits of using the nt system. It concludes with a note on the importance of practicing example problems to fully grasp the concepts.

How does the nt coordinate system simplify equations for circular motion?

What is the relationship between tangential acceleration and angular acceleration in circular motion?
