Kinematics: Reference Frames and Coordinates

This lecture covers the concept of reference frames, including the laboratory frame, geocentric frame, Keplerian frame, and center of mass frame. It also explains different coordinate systems such as Cartesian, polar, cylindrical, and spherical coordinates. The lecture delves into the definition of a point mass, trajectory, and instantaneous velocity. It further discusses the equation of motion, acceleration, and tangential acceleration. The lecture concludes with the analysis of motion in one dimension with constant acceleration.
