Changes of Reference Frames: Mechanics

This lecture covers the concept of reference frames in mechanics, emphasizing the necessity of describing motion relative to a specific frame. It explains the association of observers and measurement instruments with reference frames, highlighting the arbitrariness of frame choice. The lecture also discusses privileged frames of reference and the consistency of physical laws across different frames. It delves into the kinematics of a material point, detailing the definitions of velocities and accelerations in different frames. The dynamics in non-inertial frames, including the Coriolis force, is also explored through examples of rectilinear uniform motion on a carousel.
