D basic condition for a periodic motion 2 be shm.. is accleration directoly propptional to (- displacement)

it is very simple, every shm is periodic motion but every periodic motion is not shm .iam giving an example . earth motion is periodic but not shm whereas a watch's pendulam motion is shm as well als priodic. for shm motion there is main cond. follow which is restoring force is propotional to its distance...

The word OSCILLATERY refers to something that moves back and forth repeatedly. The word periodic refers to something that repeats after a regular amount of time. While oscillatory motion will almost certainly be periodic, not all periodic motion will be oscillatory.
A common example is the orbit of the earth around the sun. A complete orbit takes roughly 365 days and therefore this is a periodic motion. However, cannot be said to be oscillatory.
It may help to think of oscillatory motion as a certain type of periodic motion, much as a square is a certain type of rectangle.

vivek is abs right...let me just poke my nose in... Simple Harmonic is the describing term right? harmonic refers to anything that is repetitive after a certain interval of time, same as periodic (hence periodic motion) simple refers to the fact that the eqn of this motion is mathematically easy to handle (this is true, i'm not joking) so, SHM is a subset of periodic motion which has a mathematically convenient eqn...we define this further by the characteristic eqn, F = -kx

Natures follows periodicity. The day and night, seasons etc everything is repetitive. Periodic motion is the motion is the motion that repeats itself after a fixed period of time. There are many type of periodic motion; some of them is simple harmonic motion. In SHM, displacement velocity and acceleration all are sinusoids. I,e The can be represented in graphs important an fascinating chapter of mechanics.
It is a motion that repeats itself after regular time interval such that the force acting on it is directed towards a point over the linen (which it executes motion) and the force is also proportional to displacement of particle from that fixed point.
where 
k = force constant
 = a positive constant
m = mass of particle
x = displacement

A paradox is an argument that starts with apparently acceptable assumptions and leads by apparently valid deductions to an apparent contradiction. Since logic admits no contradictions, either the apparently acceptable assumptions are not acceptable, or the apparently valid
deductions are not valid, or the apparent contradiction is not a contradiction. A paradox moves us to reexamine the argument until we find out what is wrong.

simple all shm are periodic but all periodic are not shm
