Unit 8 simple harmonic motion and waves ap physics 1. An object on the end of a spring is oscillating in simple harmonic motion. Simple harmonic motion notes containing numericals, derivations, definitions, etc. An alternative definition of simple harmonic motion is to define as simple harmonic motion any motion that obeys the differential equation \ \ref11. Pdf this chapter is intended to convey the basic concepts of oscillations. 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. Simple harmonic motion study material for iit jee main. Note that the block is moving in the negative x direction at time t. Any motion that repeats itself after regular intervals of time is known as a periodic motion.
Mfmcgrawphy 2425 chap 15haoscillationsrevised 102012 4 characteristics of shm. This is done for the case of the oscillating springmass system in the table below and the three functions are shown in figure 3. All oscillatory motions are simple harmonic motion. Questions 4 the maximum acceleration of a particle moving with simple harmonic motion is. Any motion, which repeats itself in equal intervals of time is called periodic motion. Lets look at various aspects of simple harmonic motion including energy, motion, relationship with circular. Simple harmonic motion pdf candidates can download the simple harmonic motion shm pdf by clicking on below link.
Simple harmonic motion example problems with solutions pdf. Notes for simple harmonic motion chapter of class 11 physics. Note that in applying this result you must use radians. Simple harmonic motion shm notes class 11 notes edurev. Simple harmonic motion or shm is the simplest form of oscillatory motion. Professor shankar gives several examples of physical systems, such as a mass m attached to a spring, and explains what happens when such systems are disturbed. Elastic limit if exceeded, the spring does not return to its original shape. Mar 25, 2020 simple harmonic motion shm notes class 11 notes edurev is made by best teachers of class 11. Oftenly, the displacement of a particle in periodic motion can always be expressed in terms of. As you can see from our animation please see the video at 01. The examples of periodic motion are the motion of planets around the sun, motion of hands of a clock, motion of the balance wheel of a watch, motion of halleys comet around the sun observable on the earth once in 76 years. 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.
Phys 200 lecture 17 simple harmonic motion open yale. Shm arises when force on oscillating body is directly proportional to the displacement from its equilibrium position and at any point of motion, this force is directed towards the equilibrium position. Shm occurs when a particle or body is displaced from an equilibrium position and experiences a restoring force i. The focus of the lecture is simple harmonic motion. Simple harmonic motion simple harmonic motion shm occurs when the restoring force the force directed toward a stable equilibrium point is proportional to the displacement from equilibrium.
