Interesting End of Semester Project ideas wanted

AI Thread Summary
The discussion focuses on finding scientific arguments related to introductory physics concepts for a semester project. Participants seek ideas for either proving or debunking these arguments, emphasizing relevance to topics covered in class, such as Newton's laws, motion, energy, buoyancy, basic thermodynamics, and electrical/magnetism theory. Clarification is provided that this is an introductory university physics class. Suggestions for interesting debunking topics are encouraged, particularly those that align with the curriculum. Engaging with these foundational concepts can lead to insightful research projects.

We are to find a scientific argument and either prove it or debunk it through research. This was an introductory Physics class and he would prefer to stay somewhat within the scope of the class.

Does anybody have interesting debunk-ings?

What's the scope of the class? What topics have you learnt? Is this an introductory university physics class?
 
yeah I shouldve laid that out a little better. We covered Newtons law's, motion in general, energy, simple pressure/bouyancy, VERY basic Thermo, and basic elctrical/magnetism theory
 
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...
