## Important Topics for DC Pandey Mechanics Part II Solutions Chapter 11: Simple Harmonic Motion

**Simple Harmonic Motion **

In this chapter of DC Pandey Mechanics Part II Solutions, you will be introduced to the concept of Simple Harmonic Motion also expressed as SHM. Any motion in which the restoring force is directly proportional to the displacement of the body from its mean position is referred to as Simple Harmonic Motion. This restoring force always has its direction towards its mean position.

You will learn about the acceleration of a particle executing simple harmonics motion and its algebraic representation. You will also learn about the relationship between angular velocity, acceleration and time which plays an essential role in deriving Simple Harmonic Motion of a body.

**Types of Simple Harmonic Motion **

You will also be introduced to the different types of Simple Harmonic Motions in this chapter. There are two major types –

**Linear Simple Harmonic motion or Linear SHM**– when a particle moves to and fro such that it is about a fixed point (in equilibrium state) along a straight line, then its motion is termed as Linear Simple Harmonic Motion**Angular Simple Harmonic motion or Angular SHM**– when a particle or a system oscillates angular long such that it has a fixed axis then its motion is termed as Angular Simple Harmonic Motion.

**Periodic Motion and Oscillation Motion**

In this chapter, you will also learn about Periodic Motion which occurs when a motion repeats itself such that the time interval between each repetition is equal and there is no equilibrium position of the body. Oscillation motion occurs when a particle moves to and fro about a mean position. This is also a kind of periodic motion but between two extremes.
