    Balls Collision
AI Thread Summary
The discussion centers on a Year 12 student seeking assistance in creating a practical experiment related to the collision of billiard balls. The student expresses difficulty finding resources online and is open to simple experiments that demonstrate concepts like momentum and conservation. There is a mention of pendulums as an alternative, indicating a willingness to explore related topics. The urgency for help is emphasized, as the student is struggling to find a suitable practical experiment. Overall, the focus remains on the collision of billiard balls and the need for guidance in developing a related EPI.

Hi guys, first time in this forum.
seems legit.

I'm in year 12, i have to find or make a EPI (prac) to do with one of these topics.
1. Co-efficient of friction between different surfaces.
2. Strength of nylon/cotton/steel/tin string.
3. Projectile motion.
4. Bending of a beam.
5. The coefficient of restitution of a squash ball.
6. The collision of billiard balls.
7. Centripetal force, acceleration due to gravity/or along inclined.

Im going more towards No. 6, the collision of billiard balls but i can't find anything online.
if anyone could help me find/make a prac it will be very helpful. (it can be really simple)
ill be doing my best to find one for now, thanks.
Steve.

still can't find one simple enough...
really need your help guys.

pendulums would be alright.
(momentum/conservation etc)
 

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...

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

Thread 'Trying to understand the logic behind adding vectors with an angle between them'

My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
