simply because velocity is minimum. now i would like it if you think about it more i haven't studied SHM yet but these things are thinkable
anonymous
  • anonymous
den what it means here by equilibrium??
anonymous
  • anonymous
its a 11 course u alredy studied

no i did not, back in 11th i was the worst student you could ever imagine
anonymous
  • anonymous
when its velocity is zero
anonymous

i knw u are i dont ahve to imagine jk

look here in equlibrium is it means when volcity and accleration are equal?? say

anonymous

no you can't achieve equilibrium when v and x equals
anonymous
  • anonymous
v and a not x

lolz.. shayaan nice way of ans
Shayaan_Mustafa
  • Shayaan_Mustafa
i am just looking. and watching your answers. :D

ok here it simply mean that here velocity is balanced by air resistance rit then how can be accleration max means u said it help in decresing just before say
Shayaan_Mustafa
  • Shayaan_Mustafa
ok here it simply mean that here velocity is balanced by air resistance wrong statement.
anonymous
  • anonymous
then how it balanced??

do you know there is interference of acceleration due to gravity i.e. g=9.8m/s²
anonymous
  • anonymous
in SHM gravity comes but it will be equal in all move of pendulum i think so
anonymous
  • anonymous
heena simply the point where velocity of the body gets zero is equilibrium if it doesn't then there is no equilibrium point and no to&fro motion
Shayaan_Mustafa
  • Shayaan_Mustafa
again. do you know the closeness of pendulum to Earth is more accelerated than the far? I mean to say that at mean position pendulum is close to the surface of Earth therefore g attracts the pendulum and pendulum's velocity changes, change in velocity is known as acceleration.
anonymous
  • anonymous
then acceleration max. wat it sense then say?
anonymous
  • anonymous
one thing pendulum is not so big dat it move from one end to other end of earth
Shayaan_Mustafa
  • Shayaan_Mustafa
my last statement says all. try to understand my words.
anonymous
  • anonymous
yeah read shayaan's post again
anonymous
  • anonymous
u knw i have to exaplain to sir.. and like how i m arguing my sir do dat too..
Shayaan_Mustafa
  • Shayaan_Mustafa
one thing pendulum is not so big dat it move from one end to other end of earth ohh no.. here i means you displace pendulum from its mean position.
Shayaan_Mustafa

so you have viva.

yea i get wat u tring to say

nah in coching we discuss DPP dat time we have to do dat and g works same in one point and lets take ur point the their will be a minte change i think so
anonymous
  • anonymous
gettin late gtg plz give a solid reason plz...
anonymous
  • anonymous
bye...
Shayaan_Mustafa
  • Shayaan_Mustafa
yes. this change is so so so,, minute that we can't measure it.

Okay, I am gonna try to post my explanation in here hoping you would check OpenStudy in the morning (before you head for your classes). Now I am going take a simple example i.e the spring mass system. \[F_{\large{sb}} = - kx\Large{,} \small\text{ 'sb' implies force of spring on body}\] The force of the spring grows stronger with the distance the object or body covers. So let's take a look at the diagram. |dw:1327602501444:dw| The case here is that the object rest in it's natural state to move we push or provide it some velocity somehow. Now the object due to velocity it acquired would go ahead or back depending on the direction of the velocity but here what matters is that it moves from its natural position. The more the distance the object covers the more force grows stronger and gets more negative as \(F_{\large{sb}} = -kx\). From Newton's Second Law.\[F_{\large{sb}} = ma\]As the Force on the object gets more strong the acceleration or the negative acceleration gets strong too and finally the object stops attaining equilibrium but note the equilibrium it achieves is unstable not a stable one. What you wanted to know is why acceleration maximum when velocity is Zero? Well, you need only think now. Velocity gets zero at the maximum possible distance or displacement from the object natural position. Greater the distance; greater the force and greater the acceleration. Hence, acceleration is maximum when Velocity is Zero. I hope I made myself clear.

Oh crap! I drew a drawing and had more text than this. All got lost! :-/ Oh God! Why!?! I feel so bad. I did so much work! Heena the case I was or am considering is a simple spring mass system. |dw:1327603451434:dw|

heena. I HAVE studied simple harmonic motion. Maybe I can offer some insight. Simple harmonic motion is modeled as a sine wave. Simply put, \[x = \sin(t)\]Let's say the equilibrium position is defined as \(x(0)=0\) Differentiating \(x\) with respect to time to determine the velocity of the mass. \[v = \cos(t)\]Differentiating again to obtain an expression for acceleration. \[a = -\sin(t)\] If we look at a plot of all three, we can see that acceleration is 180 out of phase with position and velocity is 90 out of phase with displacement. Look here: http://www.wolframalpha.com/input/?i=plot+sin%28x%29%2C+cos%28x%29%2C+-sin%28x%29 The equilibrium position is where the blue line crosses the x-axis. Here, velocity is maximum while acceleration is minimum.
