Introduction

Simple Harmonic Motion (SHM) is a fundamental concept in physics that describes the motion of an object that oscillates about a fixed point, known as the equilibrium position. In this article, we will explore the concept of SHM and its applications, particularly in the context of a particle subjected to two mutually perpendicular SHM.

What is Simple Harmonic Motion (SHM)?

SHM is a type of periodic motion where the acceleration of the object is directly proportional to its displacement from the equilibrium position. The motion is sinusoidal in nature, meaning that the object oscillates at a constant frequency, with the displacement and velocity of the object varying sinusoidally with time.

Equations of Motion for SHM

The equations of motion for SHM can be described by the following equations:

  • x=A1cosωtx = A_1 \cos \omega t
  • y=A2sinωty = A_2 \sin \omega t

where xx and yy are the displacements of the particle in the xx and yy directions, respectively, A1A_1 and A2A_2 are the amplitudes of the motion in the xx and yy directions, ω\omega is the angular frequency of the motion, and tt is time.

Particle Subjected to Two Mutually Perpendicular SHM

The given equations describe a particle that is subjected to two mutually perpendicular SHM. This means that the particle is oscillating in two directions, xx and yy, with different amplitudes and frequencies.

Understanding the Motion

To understand the motion of the particle, we need to analyze the equations of motion. The xx-component of the motion is described by the equation x=A1cosωtx = A_1 \cos \omega t, which represents a simple harmonic motion with amplitude A1A_1 and angular frequency ω\omega. Similarly, the yy-component of the motion is described by the equation y=A2sinωty = A_2 \sin \omega t, which represents a simple harmonic motion with amplitude A2A_2 and angular frequency ω\omega.

Elliptical Motion

Since the particle is subjected to two mutually perpendicular SHM, the motion of the particle is not circular, but rather elliptical. The elliptical motion can be understood by analyzing the equations of motion. The xx-component of the motion is described by a cosine function, while the yy-component of the motion is described by a sine function. This means that the particle is oscillating in a way that its displacement in the xx-direction is proportional to the cosine of the time, while its displacement in the yy-direction is proportional to the sine of the time.

Analyzing the Motion

To analyze the motion of the particle, we can use the following steps:

  1. Determine the amplitude of the motion: The amplitude of the motion can be determined by analyzing the equations of motion. The amplitude of the xx-component of the motion is A1A_1, while the amplitude of the yy-component of the motion is A2A_2.
  2. Determine the angular frequency of the motion: The angular frequency of the motion can be determined by analyzing the equations of motion. The angular frequency of the motion is ω\omega.
  3. Determine the phase angle of the motion: The phase angle of the motion can be determined by analyzing the equations of motion. The phase angle of the motion is the angle between the xx-component and the yy-component of the motion.

Conclusion

In conclusion, the motion of a particle subjected to two mutually perpendicular SHM can be described by the equations x=A1cosωtx = A_1 \cos \omega t and y=A2sinωty = A_2 \sin \omega t. The motion of the particle is elliptical in nature, with the amplitude and angular frequency of the motion determined by the equations of motion. By analyzing the equations of motion, we can determine the amplitude, angular frequency, and phase angle of the motion.
