Homework Help Overview

The discussion revolves around measuring and explaining the gyroscopic stability of a yo-yo for a science project. The original poster expresses challenges in calculating the rotation speed due to the rapid motion of the yo-yo and seeks assistance with measurements and understanding the effects of weight removal on stability.

Discussion Character

  • Exploratory, Conceptual clarification, Assumption checking

Approaches and Questions Raised

  • Participants inquire about the equipment available for measurement, suggesting the use of slow-motion video playback. There is a mention of Newton's second law in its rotational form, prompting questions about the original poster's understanding of related concepts like moment and momentum.

Discussion Status

The discussion is ongoing, with participants exploring different aspects of the problem. Some guidance has been offered regarding measurement techniques and relevant physics principles, but there is no explicit consensus on the understanding of the concepts involved.

Contextual Notes

The original poster indicates a lack of familiarity with key physics concepts, which may affect their ability to engage with the problem fully. There is also a mention of the challenges posed by the speed of the yo-yo in measurement attempts.

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?

[tex]\vec{\tau}_{NET}=\frac{d\vec{L}}{dt}[/tex]
 
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"?
