# What is mean position and equilibrium position?

Mean Position or Equilibrium Position : It is a position of the body when the net force acting on it is zero. Phase of a particle in oscillatory motion :This represents the state of vibration of the particle at a given time.

## What is the equilibrium position of an object?

Equilibrium Position is that position where an object tends to come at rest when no external force is applied.

## What is equilibrium position in physics class 11?

Equilibrium of a Particle: When the net external force acting on a particle is zero, the particle is said to be in equilibrium. Applying the Newton’s First Law of Motion to this situation, we can say that the particle is either at rest or in uniform motion.

## What is equilibrium position in waves?

A wave can be described as a disturbance that travels through a medium from one location to another location. Consider a slinky wave as an example of a wave. When the slinky is stretched from end to end and is held at rest, it assumes a natural position known as the equilibrium or rest position.

## Why mean position is called equilibrium position?

The equilibrium position is the position of the mass when the system is stationary, in equilibrium. The mean position is the mid point of the simple harmonic motion when the spring is oscillating. Clearly for simple harmonic motion, which is symmetrical about the equilibrium position the two are equal.

## What do you mean by equilibrium position in SHM?

At the equilibrium position, the velocity is at its maximum and the acceleration (a) has fallen to zero. Simple harmonic motion is characterized by this changing acceleration that always is directed toward the equilibrium position and is proportional to the displacement from the equilibrium position.

## What is the equilibrium position of an object in simple harmonic motion?

Answer and Explanation: The equilibrium position of any simple harmonic motion is the position where the velocity of the simple harmonic motion is highest, and the acceleration of simple harmonic motion is least. The equilibrium position of the simple harmonic motion is also known as the mean position.

## What are the three types of equilibrium positions of an object?

There are three types of equilibrium: stable, unstable, and neutral. Figures throughout this module illustrate various examples.

## What is equilibrium and example?

Equilibrium is defined as a state of balance or a stable situation where opposing forces cancel each other out and where no changes are occurring. An example of equilibrium is in economics when supply and demand are equal. An example of equilibrium is when you are calm and steady.

## What are the 2 types of equilibrium?

Type of Equilibrium. Equilibrium is classified as dynamic equilibrium or static equilibrium.

## What is meant by equilibrium state?

Scientific definitions for equilibrium Physics The state of a body or physical system that is at rest or in constant and unchanging motion. A system that is in equilibrium shows no tendency to alter over time. ♦ If a system is in static equilibrium, there are no net forces and no net torque in the system. ♦

## What is the difference between equilibrium constant and equilibrium position?

Equilibrium position: a particular set of concentrations of reactant and product species. Equilibrium constant: a number that describes how far “forward” equilibrium lies for a particular system (as described by a particular equation).

## What is equilibrium position of a spring?

When a mass is hung vertically from a spring, the spring stretches. The force on the mass due to the spring is proportional to the amount the spring is stretched. There is a point at which the spring force and the weight are equal in magnitude but opposite in direction. This point is called the equilibrium position.

## How do you find the equilibrium position in SHM?

At time t = T / 4 t = T / 4 , the block reaches the equilibrium position x = 0.00 m, x = 0.00 m, where the force on the block and the potential energy are zero. At the equilibrium position, the block reaches a negative velocity with a magnitude equal to the maximum velocity v = − A ω v = − A ω .

## What is the difference between mean position and equilibrium position in SHM?

The equilibrium position of any simple harmonic motion is the position where the velocity of the simple harmonic motion is highest, and the acceleration of simple harmonic motion is least. The equilibrium position of the simple harmonic motion is also known as the mean position.

## Why velocity is maximum at mean position?

The maximum displacement of the bob from its mean position, i.e. OA or OB is called its amplitude. As the bob is its lowest position at the point O. Its potential energy is minimum while its kinetic energy is maximum. For this reason its velocity is maximum at the mean position.

## Is SHM stable equilibrium?

No, not necessarily. SHM is one possible form of oscillation about a stable equilibrium. But whether it is SHM or some other kind of oscillation depends on how the forces vary as the system moves away from equilibrium. It’s not directly about whether the system is in equilibrium.

## Why acceleration is zero at mean position in SHM?

When the mass reaches the equilibrium position, there is no restoring force. The acceleration, therefore, is zero, but the mass is moving at its highest velocity. Because of its inertia, the mass will continue past the equilibrium position, and stretch the string.

## What is SHM in physics class 11?

Simple Harmonic Motion (SHM) is a periodic rotation about the mean position of the body that shifts to and fro. On the oscillating body, the restoring force is directly proportional to its displacement and is therefore oriented towards its mean direction.

## Why is it called simple harmonic motion?

Introduction. 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.

## What happens to the equilibrium position if you keep the same mass but change the spring?

This means that the equilibrium position of a horizontal spring is independent of the mass attached to it. The same reasoning applies if you, for example, change the spring for a stiffer one but with the same natural length: the equilibrium position will be unaffected.

## What is a simple harmonic motion in physics?

Simple harmonic motion is a very important type of periodic oscillation where the acceleration (α) is proportional to the displacement (x) from equilibrium, in the direction of the equilibrium position.

## What does harmonic mean in physics?

A harmonic is a wave or signal whose frequency is an integral (whole number) multiple of the frequency of the same reference signal or wave. As part of the harmonic series, the term can also refer to the ratio of the frequency of such a signal or wave to the frequency of the reference signal or wave.

## How many types of equilibrium are there in physics?

Based on the position and stability of an object, equilibrium can be further categorized into three types: stable, unstable, and neutral equilibrium.

## What are the conditions of equilibrium?

Two conditions of equilibrium must be satisfied to ensure that an object remains in static equilibrium. Firstly, the net force acting upon the object must be zero. Secondly, the net torque acting upon the object must also be zero.
