Description: Fundamentals of Physics (PHYS 200)The focus of the lecture is simple harmonic motion. Professor Shankar gives several examples of physical systems, such as a mass M attached to a spring, and explains what happens when such systems are disturbed. Amplitude, frequency and period of simple harmonic motion are also defined in the course of the lecture. Several problems are solved in order to demonstrate various cases of oscillation.00:00 - Chapter 1. Example Equations of Oscillating Objects10:49 - Chapter 2.

Physics Oscillations part 17 (Kinetic Energy in Simple harmonic Motion) CBSE class 11
Before we go into the study of wave and its interference, its imperative that we understand the basic of a periodic motion, in particular the simple harmonic motion (SHM). In this chapter, we will be exploring the kinematics and energy of a simple harmonic motion. In the later part of this chapter, we will introduce damped oscillation where energy is lost from the oscillating system and also the forced oscillation where energy is added to the oscillating system by an external driving force. An important application to this is the phenomenon of resonance.

www.interactivephysics.com.sg Simple Harmonic Motion - Phase difference Two identical mass-spring systems can be set into oscillation. One of the systems can start its oscillation at a later time, which is decided by the user, who can then observe the phase difference between the two systems by studying the displacement-time graphs which are shown in real-time.
Fifteen uncoupled simple pendulums of monotonically increasing lengths dance together to produce visual traveling waves, standing waves, beating, and (seemingly) random motion. For more details see sciencedemonstrations.fas.harvard.edu The period of one complete cycle of the dance is 60 seconds. The length of the longest pendulum has been adjusted so that it executes 51 oscillations in this 60 second period. The length of each successive shorter pendulum is carefully adjusted so that it executes one additional oscillation in this period. Thus, the 15th pendulum (shortest) undergoes 65 oscillations. Our apparatus was built from a design published by Richard Berg [Am J Phys 59(2), 186-187 (1991)] at the University of Maryland. The particular apparatus shown here was built by our own Nils Sorensen.

www.interactivephysics.com.sg - Oscillation of a mass attached to a horizontal spring (Simple Harmonic Motion) A mass attached to a horizontal spring can be set into oscillation by extending or stretching through a small displacement. Graphs of the mass's displacement, acceleration, kinetic energy and potential energy are displayed in real time. User can vary the force constant of the spring and damping factor to see how they affect the oscillation of the mass.
At which location(s) is the kinetic energy of a mass-spring system a maximum? These videos are part of a unit of instruction created by NJCTL. Students and teachers can find additional free instruction on this topic at the site listed below. This includes the full unit presentation, homework with solutions, and assessments (teachers only).

Learn the concepts visually, using MicroStation www.Bentley.com for deeper, intuitive understanding without abstract formality and dry rigor for its own sake.
In this video, we will introduce the concept of simple harmonic motion, using a block on a spring as our example system. To analyze this system, we will apply some familiar ideas. We'll start by looking at the force exerted on a block by a spring, and then we'll go from there to think about the work done by the spring, and go on from there to define an equation for potential energy for springs. So, the system is a new one, but the concepts we'll be bringing in to analyze it are ones we have experience with.
