When a ball of cotton and a stone are dropped simultaneously, which one will fall first? or will they fall at the same time?

Ideal conditions = they both fall at the same time, but due to resistance from air they'd change.

ya if its something very light, like a feather or something, then the stone will fall first right?
anonymous
  • anonymous
ya

thanks

but only if air resistance is considered.. most of times when that question is asked.. m sure air resistance is neglected..
mayankdevnani
  • mayankdevnani
if you neglect air resistance , like in vacuum so answer is clearly that both cotton and stone are equally fall and reach equally in the same time.
mayankdevnani
  • mayankdevnani
or when we say there is air resistance so ofcourse cotton will take time.
mayankdevnani
  • mayankdevnani
ok @ShikhaDessai
anonymous
  • anonymous
thank u soooooo much @mayankdevnani i was kind of confused with 2 answers
mayankdevnani
  • mayankdevnani
welcome...sis
anonymous
  • anonymous
there are many possible conditions the cotton ball may also reach first because since you all know about air resistance and air resistance on the stone may be larger
anonymous
  • anonymous
u mean friction due to air is more on the cotton
mayankdevnani
  • mayankdevnani
yaa
anonymous
  • anonymous
not cotton you told about cotton ball
mayankdevnani
  • mayankdevnani
in short, she said that. ok @harsh314
anonymous
  • anonymous
ya i mean cotton ball
anonymous
  • anonymous
their is a difference between a piece of cotton, a ball of cotton, a molecule of cotton..........
mayankdevnani
  • mayankdevnani
i know...
anonymous
  • anonymous
ya u r absolutely right!!! i just forgot to add ball
anonymous
  • anonymous
yes so as per the question the cotton ball is in the context so we need to know that if the ball of cotton has a greater mass and aerodynamical shape such that the density is quite low and the pressure acting on the ball is less.....,,,,,,
anonymous
  • anonymous
umm i really dont know what is aerodynamical(i'm only in the 8th)....and where pressure is concerned, i think it is the acceleretion due to gravity that matters..
anonymous
  • anonymous
what do you know about air resistance
anonymous
  • anonymous
i know about friction due to air
anonymous
  • anonymous
what is friction
anonymous
  • anonymous
when two things rub against each other, friction is caused
anonymous
  • anonymous
yes what is resistance then.....
anonymous
  • anonymous
ummm i dont know
anonymous
  • anonymous
resistance means oppostion so in simple terms air resistance is the opposition of air to any moving particle.......such that it obstructs its motion.....
anonymous
  • anonymous
you got somthing
anonymous
  • anonymous
so r air resistance n friction the same?
anonymous
  • anonymous
see friction and air resistance are not identical i cant explain much because it will not be clear to you .
anonymous
  • anonymous
umm ohk
anonymous
  • anonymous
understand it like this: when any body falls from through air the particles of air collide with it as when throw a ball in water then the particles of water collide with that ball ........similarly assume about air.
anonymous
  • anonymous
hence when particles collide so the motion of the ball is obstructed tnd that is the air resistance........got it
anonymous
  • anonymous
i'm getting it a bit
anonymous
  • anonymous
ok now i understood
anonymous
  • anonymous
thanks
anonymous
  • anonymous
mention not no problem is the always ready is the ..................good to see is the you are studying is the ,.,,,,,,,,,,,,, best of luck is the dear sis ...........

what is this "is the" thing?

hahahahaha tum bhi @harsh314
anonymous
  • anonymous
oh ya i used to watch that...gopi right?
mayankdevnani
  • mayankdevnani
right!!! gopi, gulgule many more...
anonymous
  • anonymous
tumne sahi pehchana it is right is the raat ho gayi isi liye gud night is the............
anonymous
  • anonymous
ohk
mayankdevnani
  • mayankdevnani
bye...

hmm, id say that they both fall at the same time, but rather have the potential to land at different times depending on other conditions :)
anonymous
  • anonymous
so under vaccuum,both ll fall at same time eh?
anonymous
  • anonymous
ya
anonymous
  • anonymous
so the resistance offered by the air is responsible fr the increase in time fr the cotton ball?
anonymous
  • anonymous
ya right...that's what i understood due to @harsh314 's explanation
