AI Thread Summary
The discussion focuses on a science project involving the study of a yo-yo, specifically its rotation speed and gyroscopic stability. The participant is struggling to measure the fast rotation speed and seeks advice on equipment, suggesting the use of a slow-motion camera. There is confusion regarding the concepts of torque and momentum, with participants clarifying the terminology related to rotational physics. The inquiry also addresses the effects of weight distribution on the yo-yo's stability when weight is removed from one side. Understanding these principles is essential for successfully completing the project.

hi I'm from belgium and I've got a problem...
We have to do a science project and I have chose to study the yoyo
But now we got problems... we need to calculate the rotation speed but the yoyo goes to fast and we can't see it ... we have tried with a camera but still it's to fast?
Is there anybody that can help me with measurements?
other problem is the gyroscopic stability... when you remove weigt at one side, the yoyo is turning but I can't explain why? can somebody help me with these problems...
:cry:

1. What kind of equipment do you have for measuring? Perhaps a video camera that has a slow motion playback?

2. Are you familiar with Newton's second law in rotational form?

\vec{\tau}_{NET}=\frac{d\vec{L}}{dt}
 
I don't now anything of it :confused:
I thing it has all to do with the momento... :confused: more mass how bigger the momento ...
 
What's "momento"? Do you mean "moment" (as in "torque"), or do you mean "momentum"?

Thread 'Help with Time-Independent Perturbation Theory "Good" States Proof'

(Disclaimer: this is not a HW question. I am self-studying, and this felt like the type of question I've seen in this forum. If there is somewhere better for me to share this doubt, please let me know and I'll transfer it right away.) I am currently reviewing Chapter 7 of Introduction to QM by Griffiths. I have been stuck for an hour or so trying to understand the last paragraph of this proof (pls check the attached file). It claims that we can express Ψ_{γ}(0) as a linear combination of...
