Newton's Laws: Dynamics

This lecture covers Newton's laws of motion, focusing on dynamics and the relationship between force, mass, and acceleration. It explains how forces affect the motion of objects, introducing concepts like acceleration, mass, and the unit of force (Newton). The instructor discusses the causes and consequences of forces acting on objects, emphasizing the importance of understanding the relationship between force and acceleration. The lecture also delves into specific cases, such as forces at a distance and the gravitational force between masses. The famous Cavendish experiment, used to determine the mass of the Earth, is presented as an application of Newton's laws. Throughout the lecture, various symbols and units related to force and acceleration are explained.
