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. Newtonian mechanics Small-angle adn Rayleigh—Lorentz pendulum Isochronous Uniform circular motion Complex harmonic cassidau Damping Harmonic oscillator Pendulum mathematics Circle group String vibration. Retrieved from ” https: Simple harmonic motion can be considered the one-dimensional projection of uniform circular motion. At the equilibrium position, the net restoring force vanishes.

A net restoring force then slows it down until its velocity reaches zero, whereupon it is accelerated back to the equilibrium position again.

Solving the differential equation above produces a solution that is a sinusoidal function. By using this nechanics, you agree to the Terms of Use and Privacy Policy. The motion is sinusoidal in time and demonstrates a single resonant frequency. The area enclosed depends on the cqssiday and the maximum momentum. Therefore it can be simply defined as the periodic motion of a body along a straight line, such that the acceleration is directed towards the center of the motion and also proportional to the displacement from that point.

Simple harmonic motion can serve as a mathematical model for a variety of motions, such as the oscillation of a spring.


Simple harmonic motion

The motion of a particle moving along a straight line with an acceleration whose direction is always towards a fixed point on the line and whose magnitude is proportional to the distance from the fixed point is called simple harmonic motion [SHM].

The equation for describing the period. In other anapytical Wikimedia Commons. In addition, other phenomena can be approximated by simple harmonic motion, including the motion of analytkcal simple pendulum as well as molecular vibration.

A mass m attached to a spring of spring constant k exhibits simple harmonic motion in closed space. The other end of the spring is connected to a rigid support such as a wall.

As long as the system has no energy loss, the mass continues to oscillate. In Newtonian mechanicsfor one-dimensional simple harmonic motion, the equation of motion, which is a second-order linear ordinary differential equation with constant coefficients, can be obtained by means of Newton’s 2nd law and Hooke’s law for a mass on a spring. Thus simple harmonic motion is a type of periodic motion. Simple harmonic motion provides a basis for the characterization of fowlee complicated motions through the techniques of Fourier analysis.

Using the techniques of calculusthe velocity and acceleration as a function of time can be found:. Views Read Edit View history. The motion of an undamped pendulum approximates to simple harmonic motion if the angle of oscillation is small.

In the solution, c 1 and c 2 are two constants determined by the initial conditions, and the origin is set to be the equilibrium position. Note if the real space and phase space diagram are not co-linear, the phase space motion becomes elliptical.

All articles with unsourced statements Articles with unsourced statements from November Therefore, anc mass continues past the equilibrium position, compressing the spring.

In the absence of friction and other energy loss, the total mechanical energy has a constant value. The following physical systems are some examples of simple harmonic oscillator. This page was last edited on 29 Decemberat The above equation is also valid in the case when an additional constant force is being applied on the mass, i.


Once the mass is displaced from its equilibrium position, it experiences a net restoring force. However, if the mass is displaced from the equilibrium position, the spring exerts a restoring elastic force that obeys Hooke’s law. In the small-angle approximationthe motion of a simple pendulum is approximated by simple harmonic motion. For simple harmonic motion to be an accurate model for a pendulum, the net force on the object at the end of the pendulum must be proportional to the displacement.

As a result, it accelerates and starts going back to the equilibrium position.


This is a good approximation when the angle of the swing is small. If the system is left at rest at the equilibrium position then there is no net force acting on the mass.

Other valid formulations are: When the mass moves closer to the equilibrium position, the restoring force decreases. An undamped spring—mass system undergoes simple harmonic motion. The linear motion can take various forms depending on the shape of the slot, but the basic yoke with a constant rotation speed produces a linear motion that is simple harmonic in form.
