Fundamental Forces: Gravitational and Electromagnetic Interactions

This lecture covers the fundamental forces in physics, focusing on the gravitational force described by Isaac Newton and the electromagnetic force. It discusses the differentiation of interactions, the unification of interactions, and the relationship between particles and interactions. The lecture also explores the electromagnetic force, the movement of particles in magnetic fields, and the concept of electric charges. Additionally, it delves into the interaction between electric charges, the electromagnetic force, and the trajectory of particles in magnetic fields.
