Dynamics: Newton's Laws

This lecture covers the principles of dynamics, focusing on Newton's laws of motion. It starts with the first law, stating that an object in motion remains in motion unless acted upon by an external force. The second law introduces the concept of force and acceleration, emphasizing that the acceleration of an object is directly proportional to the net force acting on it. The lecture also discusses inertial frames of reference and provides examples to illustrate these concepts. Furthermore, it delves into the specific case of elastic springs, explaining how the force exerted by a spring is related to its displacement. The instructor emphasizes the importance of understanding these fundamental principles in the study of physics.
