Simple harmonic motion pdf notes

This module is concerned with one of the simplest types of periodic motion1 simple harmonic motion shm. An understanding of simple harmonic motion will lead to an understanding of wave motion in general. Simple harmonic motion is any motion where a restoring force is applied that is proportional to the displacement and in the opposite direction of that displacement. The angular frequency for simple harmonic motion is a constant by. Notes for simple harmonic motion chapter of class 11 physics. Physics i chapter 12 simple harmonic motion shm, vibrations, and waves many objects vibrate or oscillate guitar strings, tuning forks, pendulum, atoms within a molecule and atoms within a crystal, ocean waves, earthquake waves, etc. Shm occurs when a particle or body is displaced from an equilibrium position and experiences a restoring force i. It is mainly two typelinear shma particle executing linear simple harmonic motion oscillates in straight line periodically in such a way that the acceleration is proportional to its displacement from a fixed point, and is always directed towards that point.

Is independent of amplitude and acceleration due to gravity. Lets look at various aspects of simple harmonic motion including energy, motion, relationship with circular. Simple harmonic motion shm, oscillatory motion where the net force on the system. It might seem like weve started a topic that is completely unrelated to what weve done previously. Simple harmonic motion shm is caused by a restoring force. All oscillatory motions are simple harmonic motion. Simple harmonic motion 5 shm hookes law shm describes any periodic motion that results from a restoring force f that is proportional to the displacement x of an object from its equilibrium position. The frequency and period are reciprocals of each other. Mfmcgrawphy 2425 chap 15haoscillationsrevised 102012 4 characteristics of shm. The motion of the pendulum is a particular kind of repetitive or periodic motion called simple harmonic motion, or. Oftenly, the displacement of a particle in periodic motion can always be expressed in terms of. The force magnitude depends only on displacement, such as in hookes law. Any motion, which repeats itself in equal intervals of time is called periodic motion. Simple harmonic motion or shm is the simplest form of oscillatory motion.
