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?

    but only if air resistance is considered.. most of times when that question is asked.. m sure air resistance is neglected..

    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.

    or when we say there is air resistance so ofcourse cotton will take time.

    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

    u mean friction due to air is more on the cotton

    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.....,,,,,,

    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..

    when two things rub against each other, friction is caused

    resistance means oppostion so in simple terms air resistance is the opposition of air to any moving particle.......such that it obstructs its motion.....

    see friction and air resistance are not identical i cant explain much because it will not be clear to you .

    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.

    hence when particles collide so the motion of the ball is obstructed tnd that is the air resistance........got it

    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 :)

    so the resistance offered by the air is responsible fr the increase in time fr the cotton ball?
