Introduction to Oscillatory Motion and Waves. What do an ocean buoy, a child in a swing, the cone inside a speaker, a guitar, atoms in a crystal, the motion of chest cavities, and the beating of hearts all have in common? They all oscillate—-that is, they move back and forth between two points.
Oscillatory Motion. 4.1 The Important Stuff. 4.1.1 Simple Harmonic Motion. In this chapter we consider systems which have a motion which repeats itself in time, that is, it is periodic. In particular we look at systems which have some coordinate (say, x) which has a sinusoidal dependence on time.

OSCILLATIONS AND WAVES. 4.1 Harmonic Oscillation. 4.1.1 Springs and the Simple Harmonic Motion (SHM) Periodic Motion. A periodic motion is a motion of an object that regularly returns to a given position after a fixed time interval. Simple Harmonic Motion (SHM) The force is proportional to the distance from the equilibrium position.
An oscillation is a back and forth motion of an object between two points of deformation. An oscillation may create a wave, which is a disturbance that propagates from where it was created. The simplest type of oscillations and waves are related to systems that can be described by Hooke’s law.
12 Μαρ 2024 · Table of contents. Figure 5.1.1 5.1. 1: There are at least four types of waves in this picture—only the water waves are evident. There are also sound waves, light waves, and waves on the guitar strings. (credit: John Norton)
3 Απρ 2019 · The tire swing is a good approximation of a simple pendulum. Pull the tire back a short distance and release it so that it oscillates as a pendulum in simple harmonic motion with a small amplitude. Measure the period of the oscillations and calculate the length of the pendulum from the expression. π = 2 T / g.
