Central Forces in Physics

This lecture covers the concept of central forces in physics, focusing on the flatness of trajectories, examples of central forces like electrostatic force and nuclear fusion potential, and the application of Newton's laws to elliptical trajectories. The instructor explains the equal areas law, the motion of planets, and the consequences of central ethactive forces. The lecture also delves into polar cords, elliptical trajectories, and the behavior of objects in a central force field.
