first of all, hi. I am new here, I am a high school student, love my physics.
anyway, i came across this when i was doing an experiment for school...it doesn't really relate to my experiment but i found it interesting and i'd like to know why it happens.
I dropped a marble through a cylindrical container of water, of radius approx. 5cm, and as expected it fell reasonably quickly, though some resistance was noted.
I repeated this with a container of radius approx 2cm, and i noticed it took significantly longer for the marble to reach the bottom.
can anyone explain why this is to me? All i could think of was the gravitational attraction between the two masses, but i would've thought it would be too small to have such a significant effect...
if anyone can tell me why this happens i'd appreciate it.
also, what qualifications/degrees/etc do you guys have and how long have you studied for? I'm quite good in science & math compared with other students at my level, but I'm utterly baffled by the majority of the questions posted on this board just wondering what I am in for if i want to be at that level some day
