SUMMARY

The discussion focuses on measuring the rotation speed and gyroscopic stability of a yo-yo for a science project. Participants suggest using slow-motion video equipment to capture the fast rotation. The concept of gyroscopic stability is linked to Newton's second law in rotational form, specifically the relationship between torque and angular momentum. Clarification is sought regarding the terminology, particularly the distinction between "moment" and "momentum."

PREREQUISITES
  • Understanding of Newton's second law in rotational dynamics
  • Familiarity with concepts of torque and angular momentum
  • Knowledge of video analysis techniques for motion capture
  • Basic physics terminology related to rotational motion
NEXT STEPS
  • Research slow-motion video equipment for analyzing fast-moving objects
  • Study Newton's second law in rotational dynamics
  • Learn about torque and its effects on rotational stability
  • Explore the differences between momentum and moment in physics
USEFUL FOR

Students conducting physics experiments, educators teaching rotational dynamics, and hobbyists interested in the mechanics of yo-yos.

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"?
