Forces and Friction: Understanding Mechanical Interactions

This lecture covers the concept of elastic deformation and Hooke's Law, explaining how the force exerted by a spring is proportional to its displacement. It also delves into the fundamental forces, including dry friction models and coefficients, and the impact of surface contact on friction. The presentation continues with an exploration of viscous friction, detailing how it depends on velocity and fluid viscosity. The lecture concludes with a practical application of Newton's laws in ballistic scenarios, providing a step-by-step guide to problem-solving techniques.
