Forces in Physics

This lecture covers the fundamental concepts of forces in physics, including Newton's laws, gravitational forces, and friction. It explains how forces affect the motion of objects, the relationship between mass and acceleration, and specific types of forces such as gravitational and contact forces. The lecture also delves into practical examples like Cavendish's experiment and the calculation of frictional forces. Additionally, it explores the impact of forces on objects in different scenarios, such as free fall and static equilibrium.
