Question

at equilibrium position acceleration of paticle is maximum in simple harmonic motion ...give reason y is it so..

Answer 1

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

Answer 2

den what it means here by equilibrium??

Answer 3

its a 11 course u alredy studied

Answer 4

no i did not, back in 11th i was the worst student you could ever imagine

Answer 5

when its velocity is zero

Answer 6

i knw u are i dont ahve to imagine
jk

Answer 7

thanks

Answer 8

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

Answer 9

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

no

Answer 10

no you can't achieve equilibrium when v and x equals

Answer 11

v and a not x

Answer 12

lolz.. shayaan nice way of ans

Answer 13

i am just looking.
and watching your answers. :D

Answer 14

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

Answer 15

ok here it simply mean that here velocity is balanced by air resistance

wrong statement.

Answer 16

then how it balanced??

Answer 17

only 5 min i had cmn quick quick....

Answer 18

do you know there is interference of acceleration due to gravity i.e. g=9.8m/s²

Answer 19

in SHM gravity comes but it will be equal in all move of pendulum i think so

Answer 20

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

Answer 21

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.

Answer 22

then acceleration max. wat it sense then say?

Answer 23

one thing pendulum is not so big dat it move from one end to other end of earth

Answer 24

my last statement says all.
try to understand my words.

Answer 25

yeah read shayaan's post again

Answer 26

u knw i have to exaplain to sir.. and like how i m arguing my sir do dat too..

Answer 27

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.

Answer 28

so you have viva.

Answer 29

yea i get wat u tring to say

Answer 30

thanx ishaan94

Answer 31

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

Answer 32

gettin late gtg plz give a solid reason plz...

Answer 33

bye...

Answer 34

yes. this change is so so so,, minute that we can't measure it.

Answer 35

tc. bye. good luck.

Answer 36

Regards,
Read my Profile. :D

Answer 37

ur profile y?? is der any impt info for me ...

Answer 38

hehehehhehehe.....
no no.. its my sign, say. :D

Answer 39

ishaan want to kill u bhudhu kam k time to kuch ate ni ho...
:"( agar sir ne y ques mjse pucha remember voice of knocking at ur door will come !!!!!

Answer 40

ishaan94 to gaya. hahahahaa...

Answer 41

acha laga ap 2no se mil k.. nice fun..

Answer 42

well bye friends. i have to go now. its university tomorrow. tc all and good luck for new day.

Answer 43

heena are you here?

Answer 44

Bye shayaan!

Answer 45

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.
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.

Answer 46

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.
