Nice..

Oscillation and Vibration both are guided motions about a fixed point ,, commonly called mean position..

In oscillation the distance from the fixed point remains constant and its trajectory is commonly an arc of circle whose radius is "the distance of oscillator from point of oscillation",, like in simple pendulum!!

Consider such a motion(forget gravity, m talkin of trajectory); thenwhat if we make the distance from that point of oscillation zero. Means the particle will now be stationary, but if you take projection of this oscillation on a plane, the particle will appear to move to and fro about a point in fixed line,, what we call is vibration!!

I hope you got the difference..

I want to know the physical significance....( Not by the formula of eccentricity of ellipse...)

That is in terms of distance from focus and directrix.

u all must have read about elasticity limit in NCERT.

thats d key,, when baloon reaches a height , in normally filled baloon pressure inside keeps on constantly rising, this stress-strain curve reaches elasticity limit, n bursts..

Thus in hot-air baloon where burning gases are used, flame is made to decrease and there is a certain limit to rise ..

well i have jus joined this site,, rite now..

i saw this interesting question..

Generation of all forces is somewhere due to electromagnetism,, which is described as basic force of nature..

Actually forces exist between every matter. But they increase or decrease depending on mass and the obects' mutual equilibrium.There is even attraction between uncharged and charged particles...

But when we talk of only charges,, there is internal matter instability,, that arises due to sense of rotation of quarks,, up-quarks and down-quarks,, u can surely search bout it on net,, if don blieve me.. Even quantisation in one-third or two-third electronic charge is possible due to these quartz... This is the basic reason of force,, because these opposite spins tend to generate electric winds and come near,, or same spins go away...

This was observed never explained.. Observation named Coulomb's law.. Explanation given by modern scientists,, on different theories ,, mine is one of them...
