AI Thread Summary
The discussion centers on the ball drop phenomenon, where a smaller ball stacked on a larger one can achieve greater elevation when dropped onto a hard surface. Participants are encouraged to investigate this effect and design a multi-ball system, using up to four balls, to maximize the height of the top ball. Relevant resources are shared to aid in understanding the physics behind the phenomenon. There is a question raised about whether this topic relates to the IYPT question for 2008. The exploration of this phenomenon could lead to interesting insights in physics and engineering design.

sombodyyyyyyyyy hellllllllllp me

Astroblaster:
When a large ball is dropped, with a smaller one stacked on top of it, onto a hard surface, the smaller ball will often rise much higher than it would if dropped onto the same surface by itself while the larger ball hardly bounces at all. Investigate this phenomenon and design a multiple-ball system, using up to 4 balls, that will reach the greatest elevation of the top ball.

ahh. is this the IYPT question for 2008. ?
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Voltmeter readings for this circuit with switches'

TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
