Physics 1: Small Oscillations and Equilibrium Points

This lecture covers the physics of small oscillations around equilibrium points, focusing on the stability of these points and the behavior of harmonic oscillators. It also discusses the pulsation of oscillations, the movement of material points attached to rods, and the example of a rigid pendulum. The instructor explains the concepts of unstable equilibrium and the conditions for stability in different scenarios, such as identical reports from various sources. Additionally, the lecture delves into the gravitational fields, central force, and angular momentum, exploring the conservation of angular momentum and Kepler's laws. It also touches on historical figures like Aristarchus of Samos, Galileo, and Newton, highlighting their contributions to understanding celestial body movements.
