Unformatted text preview: Alta Physics Chapter 11 Vibrations and Waves Alta Physics Simple Harmonic Motion When a vibration or an oscillation repeats itself back and forth over the same path, the motion is said to be periodic . The most common oscillation come from springs and you will recall from earlier chapters that the description of a spring’s oscillation requires some vocabulary. Alta Physics Oscillation of a Mass on a Spring Top picture is “rest position”; x = 0 Bottom picture is “stretched position” Here x represents the displacement . Maximum displacement is called the amplitude . One cycle refers to one complete to and fro motion. The period, T represents the time for one cycle. The frequency, f is the number of cycles in a given time period, usually one second. Alta Physics Relationship between Frequency and Period Frequency – the number of cycles in one second...
