Curvilinear Motion and Rotation — Lesson 3

This lesson covers the concept of curvilinear motion, focusing on rotation about a point as the simplest case of curvilinear motion. The lesson introduces the general rules for curvilinear motion, explaining the Cartesian definition of the motion of an object and the concept of a position vector. It also discusses the difference between the Cartesian coordinate system and the curvilinear coordinate system. The lesson then delves into the definitions of velocity and acceleration in the context of curvilinear motion. It provides an example of a particle tracing a circular rotation about a point, and explains how to find the maximum velocity of the particle and the amplitude of the periodic motion.
