![]() Angular Oscillation is the oscillation when a body is allowed to rotate freely about a given axis. Its acceleration is always toward a fixed point in the line and is proportional to its distance from the fixed point. Simple harmonic motion is defined as a periodic motion along a straight line. Before moving ahead, one should know the definitions of the basic terms given below. \(F_ = – k x\), the negative sign shows that the force is acting against the displacement x.Here, we will give you brief notes on conditions for an angular harmonic oscillator to be angular shm and will be discussing all the terms used here. The restoring force which tries to restore the deformation of spring can be expressed by Hooke’s law which is, When the block moves away from the wall horizontally, spring tries to restore and due to this oscillatory motion starts. Suppose a block of mass m is tied up with long spring (with spring constant k) at one end and its other end is fixed on the wall. Hooke’s law can be explained with the help of the following example. In this motion, the restoring force is directly proportional to its displacement from its equilibrium position. ![]() Simple Harmonic Motion (SHM) – An Oscillatory MotionĪ simple form of oscillatory motion is Simple Harmonic Motion (SHM). For example, the motion of the car wheel is periodic but it is not oscillatory whereas the motion of stringed object nailed at the wall is both periodic as well as oscillatory. A periodic motion may or may not be an oscillatory motion. Each oscillatory motion is always a periodic motion but it is not necessary that each periodic motion is oscillatory. The oscillatory motion should not be confused with periodic motion. But in general, when the object moves at high frequencies then the object is vibrating and when the movement takes place at low frequencies it is said that the object is oscillating. There is no significant difference between these two terms. Objects, which are oscillating, can be said that they are vibrating. After some time when oscillatory motion stops due to friction of medium in which the object is oscillating, the oscillating object comes to rest on this point. The equilibrium position of the oscillatory motion is the position about which the oscillations occur and in each oscillation, it is mandatory for the oscillating object to pass through this point. ![]()
