Small Oscillations in Classical Mechanics Lecture 1

Small Oscillations in Classical Mechanics Small oscillations are an important concept in classical mechanics, particularly when studying the stability of equilibrium points and analyzing systems near these points. When a system is displaced slightly from its equilibrium position and the resulting forces are approximately linear, the system undergoes small oscillations. This is a key principle […]

Central Force Problem and Kepler’s Laws

Central Force Problem and Kepler’s Laws The central force problem, especially in the context of gravitational interactions, provides the foundation for understanding the motion of celestial bodies. Johannes Kepler, through meticulous observation and analysis, formulated three fundamental laws describing planetary motion. These laws, derived from the central force problem governed by Newtonian gravity, revolutionized our […]

Central Force (Problem based on effective potential)

The central force problem is a classical mechanics issue where a particle is subject to a force that is directed towards a fixed point (the center) and whose magnitude depends only on the distance from the center. This problem is elegantly addressed using the concept of effective potential, which combines both the actual potential energy […]

Central Forces and Effective Potential

Central Forces and Effective Potential Central forces are pivotal in understanding the dynamics of systems where the force between two bodies depends solely on the distance between them and acts along the line connecting their centers. One powerful tool in analyzing such systems is the concept of effective potential, which combines the central potential and […]
