MIT Vibrations and Waves Problem Solving Help Videos, Fall 2012 - 1. Simple Harmonic Motion & Problem Solving Introduction

View the complete OCW resource: http://ocw.mit.edu/resources/res-8-005-vibrations-and-waves-problem-solving-fall-2012/ Instructor: Wit Busza We discuss the role problem solving plays in the scientific method. Then we focus on problems of simple harmonic motion - harmonic oscillators with one degree of freedom in which damping (frictional or drag) forces can be ignored. *NOTE: These videos were originally produced as part of a physics course that is no longer available on OCW.* Chapters 0:00:00 Title slate 0:00:27 Why learn about waves and vibrations? 0:01:31 What is the Scientific Method? 0:03:19 Ideal spring example 0:10:27 Oscillations of a bird after landing on a branch (example of a more qualitative understanding of a physical phenomenon). 0:12:53 The LC circuit (charge and current oscillations in an electrical circuit). 0:24:17 Motion of a mass hanging from a spring (a simple example of the scientific method in action). 0:25:07 Oscillation of a hanging ruler pivoted at one end (example of SHM of a rigid body—problem involves the understanding of angular motion, torques and moment of inertia).
