Forces in Physics

This lecture covers fundamental forces in physics, including gravitational and electromagnetic interactions. It explains concepts such as the force of gravity, Coulomb's law, magnetic forces, and the Lorentz force. The lecture also touches on strong and weak interactions, deformation forces, and friction models. The instructor discusses topics like gravitational waves, the graviton particle, and the equations of Maxwell. Practical examples of friction coefficients and models for viscous friction are presented. The lecture concludes with the Hooke's law for spring force and plastic deformation. Overall, it provides a comprehensive overview of the forces governing physical interactions.
