Physics - Module 2 - Introduction to Statics and Dynamics: Hooke's Law

The video explores Hooke's Law, focusing on the relationship between force and displacement in elastic objects. It explains the concepts of internal and external forces, tension, compression, and Newton's Third Law. Through practical examples, such as a toy gun and a rubber snake, the video illustrates how Hooke's Law applies to real-world scenarios. It covers the calculation of spring constants, the construction of force-displacement graphs, and the concept of proportionality limits. The video concludes with a summary of key points, emphasizing the importance of understanding these principles for exams.
