Frames of Reference: Physics 1

This lecture introduces the concept of frames of reference in physics, emphasizing that the laws of physics are the same in all frames but can take different forms. It explains how to describe the movement of a system in a frame of reference and the importance of choosing a reference frame. The lecture covers the privileged frames of reference, the association of observers with frames, and the characteristics of non-deformable solid systems. It also discusses the Galilean frames of inertia and the arbitrary nature of choosing a reference frame. The concept of a reference frame as a set of non-coplanar points is highlighted, along with the role of observers and their instruments.
