Newton's Laws of Motion

This lecture covers the fundamental concepts of Newton's Laws of Motion, including the relationship between force and momentum, the second law in mathematical terms, the third law of action-reaction, and the conservation of momentum. It also discusses the errors to avoid when applying the action-reaction law, the definition of a system under consideration, and the distinction between internal and external forces. The lecture concludes with a detailed explanation of the four fundamental interactions in physics: gravitational, electromagnetic, strong nuclear, and weak nuclear forces.
