Oscillations Introduction

Introduction to oscillation:

In scientific way, there are numerous kinds of motion, such as linear motion, uniformly accelerated motion, non-uniform motion, circular motion, translatory motion, rotational motion, one dimensional motion, two dimensional motion, vibratory motion, periodic motion, oscillatory motion etc. Here we discuss the oscillatory motion.Please express your views of this topic Newtons 1st Law of Motion by commenting on blog.


Explanation and examples of oscillatory motion:


A motion that repeats itself repeatedly about its mean position, such that it remains confined within two well-defined limits (called extreme positions) on either side of the mean position or from the equilibrium, position is called oscillatory motion. It is also called as the vibratory motion. For example, the motion of the Halley’s comet, motion of the earth, phases of moon, the bob of the simple pendulum, the motion of the bar magnet when it is freely suspended.


Some of the common examples are as follows:

The liquid contained in a U tube is oscillatory if it is displaced by a small distance.
The motion of the loaded spring if it being displaced by a small distance.
When a small glass ball or the metallic ball is dropped along the walls of the bowl, it executes the oscillatory motion.
When a piece of wood floating over the surface of the liquid is pressed down and released, it executes oscillatory motion.
If a tunnel is dug along the diameter of the earth and a body is dropped in the tunnel, then the body will not come to rest at the centre of the earth. It will execute the oscillatory motion inside the tunnel about the centre of the earth.Is this topic Force Formula hard for you? Watch out for my coming posts.

Conclusion for oscillation:


We can conclude that the periodic motion or the bounded motion of a particle about its position may be called as the oscillatory motion. It easily follows that all oscillatory motion is periodic motion but not every periodic motion is oscillatory. Remember that the time taken to complete one oscillation by a body, which executes the oscillatory motion, is constant and that time is called the time-period. The reciprocal of the time-period is called frequency or the number of oscillations in one second is called frequency.
