What is SHM and its characteristics?


Sharing is Caring


In simple harmonic motion, the acceleration of the particle is directly proportional to its displacement and directed towards its mean position. The total energy of the particle exhibiting simple harmonic motion is conserved. SHM is a periodic motion.

Why SHM is called simple?

If you look at a text on Simple Harmonic Motion in a physics book you see that ‘Simple’ refers to the ideal case where there is no friction, viscosity etc. Indeed, ideal cases are usually the simples in Physics.

What is energy in SHM?

The total energy in simple harmonic motion is the sum of its potential energy and kinetic energy.

What is the frequency of SHM?

The frequency of SHM is 100 Hz.

What is constant in SHM?

The only thing that remains constant for one particle performing SHM is its periodic time or simply time period.

Which chapter is SHM?

Simple Harmonic Motion is one of the easiest chapters in 11th Physics.

What is simple harmonic motion with Example Class 11?

The back and forth, repetitive movements of the swing against the restoring force is the simple harmonic motion. The pendulum oscillating back and forth from the mean position is an example of simple harmonic motion. Bungee Jumping is an example of simple harmonic motion.

What is SHM dimensional formula?

Mโˆ˜LTโˆ˜

How is SHM formula derived?

The velocity of the mass on a spring, oscillating in SHM, can be found by taking the derivative of the position equation: v(t)=dxdt=ddt(Acos(ฯ‰t+ฯ•))=โˆ’Aฯ‰sin(ฯ‰t+ฯ†)=โˆ’vmaxsin(ฯ‰t+ฯ•). Because the sine function oscillates between โ€“1 and +1, the maximum velocity is the amplitude times the angular frequency, vmax = Aฯ‰.

What is amplitude of SHM?

The amplitude of a SHM can be defined as the maximum displacement of a particle from its mean position.

What are the applications of SHM?

Simple harmonic motion and obtains expressions for the velocity, acceleration, amplitude, frequency and the position of a particle executing this motion. Its applications are clock, guitar, violin, bungee jumping, rubber bands,diving boards,eathquakes, or discussed with problems.

What is the full form of SHM?

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 is Velocity in SHM?

Velocity is distance per unit time.

Is SHM a sine wave?

Sinusoidal Equations The motion of an object in simple harmonic motion is sinusoidal. What do we mean by that? We mean that values like displacement, velocity and acceleration vary in the shape of a sine or cosine curve. A sine curve looks like the red curve below.

What are the two basic characteristics of SHM?

Solution : The two basic characteristics of a simple harmonic motion :
(i) Acceleration is directly proportional to displacement.
(ii) The direction of acceleration is always towards the mean position, that is opposite to displacement.

What is SHM mention any four properties?

1- A restoring force must act on the body. 2- Body must have acceleration in a direction opposite to the displacement and the acceleration must be directly proportional to displacement. 3- The system must have inertia (mass). 4- SHM is a type of oscillatory motion.

What are the five important terms of simple harmonic motion?

  • Oscillating system. Any system that always experiences a force acting against the displacement of the system (restoring force).
  • Restoring force. A force that always acts against the displacement of the system.
  • Periodic Motion.
  • Amplitude.
  • Period.
  • Frequency.
  • Hertz.
  • Angular Frequency.

What is K in SHM equation?

The letter K that is seen in several expression related to Simple Harmonic Motion (SHM) is a constant. It is usually called spring or force constant (Nยทm-1). Was this answer helpful?

What is the phase of SHM?

Definition- The phase of Simple harmonic motion is defined as an angular term which represents the state of a particle from the mean position at a certain instant. Here, x = Displacement of particle from mean position at time ‘t’. The quantity $left( omega t + theta right)$is known as phase at instant ‘t’.

What is phase angle in SHM?

The displacement of a particle in SHM is given by ` x=A sin ( omega t+ alpha)` . The angle `(omegat+alpha)` is called the phase angle or simply the phase of SHM.

What is the difference between SHM and oscillation?

So, the differences between simple harmonic motion and oscillatory motion are: – Oscillatory motion is the general term for periodic motion but Simple harmonic motion is the simplest type of periodic motion.

Is frequency constant in SHM?

One interesting characteristic of the SHM of an object attached to a spring is that the angular frequency, and therefore the period and frequency of the motion, depend on only the mass and the force constant, and not on other factors such as the amplitude of the motion.

Why time period is constant in SHM?

The period stays constant because the solutions can be rescaled at will. So if you have some valid motion ฮธ(t) describing the pendulum’s angle ฮธ as a function of time t, then you can scaled this motion up or down by any factor s and still get a valid motion sฮธ(t).

Is kinetic energy constant in SHM?

EXPLANATION: From the above discussion, we can say that the time period is what remains constant in a simple harmonic motion. So option 2 is correct. The kinetic energy and potential energy depends on the displacement (y) that varies with time, so they are not constant during the motion.

What should I study before SHM?

Before getting to SHM, it is important to understand oscillatory and periodic motion. An oscillatory motion is the to and from motion executed by an object about a mean point. A simple example is the motion of a pendulum about its mean position.
