This lecture covers Newton's three laws of motion, starting with a historical perspective on Aristotle's physics and leading to Newton's groundbreaking work. It explains the concepts of momentum, forces, and the relationship between interactions and mass. The conservation of momentum and the action-reaction principle are thoroughly discussed, along with examples illustrating these laws in different reference frames. The lecture also delves into the application of Newton's laws in non-inertial reference frames, such as those undergoing non-uniform translation or rotation.
