Homework Help Overview

The discussion revolves around calculating the frequency of an object moving in a vertical circle, specifically in the context of grade 12 physics. The original poster seeks an equation for frequency in terms of tension, radius, and mass.

Discussion Character

  • Exploratory, Assumption checking, Problem interpretation

Approaches and Questions Raised

  • Participants discuss potential formulas for frequency, with one suggesting a specific equation involving tension, weight, and radius. Another participant questions whether the same equation applies to a horizontal circle, indicating a need for clarification on the differences between the two scenarios.

Discussion Status

The conversation is ongoing, with participants exploring different interpretations of the problem. One participant has provided a formula, while others are questioning its applicability to the specific context of a vertical circle versus a horizontal circle. Guidance has been offered regarding the nature of the forum and the importance of collaborative learning.

Contextual Notes

There is a mention of the distinction between vertical and horizontal circular motion, with considerations of gravity and tension affecting the dynamics. The original poster's grade level indicates a specific educational context that may influence the complexity of the discussion.

"Obtain an equation for the frequency in terms of tension, radius, and mass"

I'm having serious trouble with this question.

By the way...this is grade 12 physics...
 
Physics news on Phys.org
I'm not sure if this is correct, but I came up with the formula frequency (f)= square root (tension+weight)/2pi*radius*sqareroot (mass). This would be the frequency expressed in terms of tension, radius, and mass at the top of a vertical circle, but I'm not sure whether this pertains to your situation or not.
 
this was for a horizontal circle...would the equation be the same?

btw, thank you!
 
Pete is evidently considering a vertical circle. For an ideal horizontal circle the situation is simpler (in ideal conditions, you don't consider the gravity pulling the string downward, and the length of the string can be considered to be equal tot he radius).

The tension in the string is what provides the Fc, so therefore the formula for Fc is manipulated to find a statement for v.

Then this result is equated to the basic equation for tangential speed (you know, circumference over period, or circumference times frequency).

BTW, Pete: hold back on simply giving out an answer. THis forum is for helping others, not just giving them answers. Good solution still (but for the wrong problem).
