What are the major difference between simple harmonic motion and damped harmonic motion?

The difference is what happens over time: Simple Harmonic motion has the same amplitude over time. A perfectly frictionless pendulum will swing back and forth the same distance over and over again. Damped oscillation weakens over time; this applies to most real-life examples of harmonic motion, at least in some regard.

What is simple harmonic motion?

simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side.

What do you mean by damped harmonic motion?

Damped harmonic motion is a real oscillation, in which an object is hanging on a spring. Because of the existence of internal friction and air resistance, the system will over time experience a decrease in amplitude. The decrease of amplitude is due to the fact that the energy goes into thermal energy.

What is the difference between SHM and oscillation?

So, the differences between simple harmonic motion and oscillatory motion are: – The restoring force acting on the particle for oscillatory motion is not specified but in simple harmonic motion it is directly proportional to the displacement of the object and acts in the opposite direction.

Which one of the following motions is not simple harmonic?

The motion of a planet around the sun is a periodic motion but not a simple harmonic motion. All other given motions are the examples of simple harmonic motion.

Which factors are required to explain the motion of a body executing simple harmonic motion?

What conditions must be met to produce SHM? The restoring force must be proportional to the displacement and act opposite to the direction of motion with no drag forces or friction. The frequency of oscillation does not depend on the amplitude.

What is a harmonic system?

In an electric power system, a harmonic of a voltage or current waveform is a sinusoidal wave whose frequency is an integer multiple of the fundamental frequency. Harmonic frequencies are produced by the action of non-linear loads such as rectifiers, discharge lighting, or saturated electric machines.

What is the opposite of simple harmonic motion?

Unlike simple harmonic motion, which is regardless of air resistance, friction, etc., complex harmonic motion often has additional forces to dissipate the initial energy and lessen the speed and amplitude of an oscillation until the energy of the system is totally drained and the system comes to rest at its equilibrium …

What is the significance of studying simple harmonic motion?

The study of Simple Harmonic Motion is very useful and forms an important tool in understanding the characteristics of sound waves, light waves and alternating currents. Any oscillatory motion which is not simple Harmonic can be expressed as a superposition of several harmonic motions of different frequencies.

What are the properties of simple harmonic motion?

Simple harmonic motion. Simple harmonic motion, in physics, repetitive movement back and forth through an equilibrium, or central, position, so that the maximum displacement on one side of this position is equal to the maximum displacement on the other side. The time interval of each complete vibration is the same,…

Why does simple harmonic motion occur?

“Simple harmonic Motion occurs when a particle or object moves back and forth within a stable equilibrium position under the influence of a restoring force proportional to its displacement.” It is used to model many real-life situations in our daily life. Let’s understand some of them. 1.

Is a bouncing ball an example of simple harmonic motion?

A bouncing ball is an example of a dampened wave. In essence, every time the ball bounces, it looses energy, and the next bounce is not as long, so it gets shorter on each bounce. An example of simple harmonic motion is the swing in the playground, or a something swinging on a rope.
