Simple Harmonic Motion





Abstract 
MIT Physics professor Walter Lewin explains Simple Harmonic Motion. In mechanics and physics, simple harmonic motion is a type of periodic motion where the restoring force is directly proportional to the displacement. It can serve as a mathematical model of a variety of motions, such as the oscillation of a spring. In addition, other phenomena can be approximated by simple harmonic motion, including the motion of a simple pendulum as well as molecular vibration. Simple harmonic motion is typified by the motion of a mass on a spring when it is subject to the linear elastic restoring force given by Hooke's Law. The motion is sinusoidal in time and demonstrates a single resonant frequency. Simple harmonic motion provides a basis for the characterization of more complicated motions through the techniques of Fourier analysis.

Chaos and Fractals in Simple Physical Systems...





Abstract 
Chaos and Fractals in Simple Physical Systems as Revealed by the Computer. By Frank Varosi and James A. Yorke (Media magic) This video features studies of three important kinds of physical systems: The swinging pendulum, the double well duffing oscillator, and the laser beam oscillator. When a pendulum is forced Periodically (so that it continues to oscillate), its motion can become periodic or choatic, depending on the amount of forcing. The study of a swinging includes extraordinarily complicated "fractal" sets. Using the computer's zoom feature, the video focuses on such fractal sets and displays their beauty and complexity. in a similar manner the video the video examines the double well Duffing oscillator, which simulates a ball rolling between two basins. By means of computer graphs one can see how geometric patterns can abruptly change discontinuously as the degree of forcing is slightly modified. the final segment uses a laser beam oscillator to investigate "attractors",what they are and how they change as a physical parameter is slowly varied. Throughout the 50 min long presentation Professor Yorke describes the scientific meaning of the accompanying computer images.

Guitar Harmonics and Chords





Abstract 
In acoustics and telecommunication, a harmonic of a wave is a component frequency of the signal that is an integer multiple of the fundamental frequency. For example, if the fundamental frequency is f, the harmonics have frequencies f, 2f, 3f, 4f, etc. The harmonics have the property that they are all periodic at the fundamental frequency, therefore the sum of harmonics is also periodic at that frequency. Harmonic frequencies are equally spaced by the width of the fundamental frequency and can be found by repeatedly adding that frequency. F...
