asked in category: General Last Updated: 13th May, 2020# What is mean position in SHM?

**Simple Harmonic Motion**(

**S.H.M**)

**position**or

**mean position**is its amplitude. Its S.I. Its direction is always away from the

**mean**or equilibrium

**position**. Period: The time taken by a particle to complete one oscillation is its period.

Similarly, 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. For this reason its **velocity is maximum** at the **mean position**. The bob is its highest point at either of its extreme **positions**. Here its potential energy is **maximum** while the kinetic energy is zero.

Subsequently, question is, what do you mean by amplitude of SHM? The **amplitude** is simply the maximum displacement of the object from the equilibrium position. So, in other words, the same equation applies to the position of an object experiencing **simple harmonic motion** and one dimension of the position of an object experiencing uniform circular motion.

Accordingly, why SHM is called simple?

In mathematics if any variable is written in terms of sines and cosines ( that too going on both side of zero ) we call such function “harmonic”. In **simple** terms to and fro periodic motion(or oscillations simply) is **called** harmonic motion from mathematical point of view.

How do you determine SHM?

Find the acceleration from the equation representing the displacement and try to relate. The other method is that an **SHM** usually involves conservation of energy. So try finding total energy. If it is constant, then look for spring like properties, which we usually find in an **SHM**.
