Calculating Frequency for a Vertical Circle

    Frequency
In summary, a person is seeking help with an equation for frequency in terms of tension, radius, and mass. A solution is offered using the formula frequency (f)= square root (tension+weight)/2pi*radius*sqareroot (mass) for a vertical circle, but it may not be applicable to their specific situation. Another individual suggests considering an ideal horizontal circle and manipulating the formula for centripetal force to find an equation for velocity. It is also mentioned to not simply give out answers on this forum.

Someone help!

"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...

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 verticle 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).
 

1. What is an equation of frequency?

An equation of frequency is a mathematical expression that relates the number of occurrences of a repeating event (e.g. cycles, waves, oscillations) to the unit of time in which it occurs. It is often used to describe the periodic nature of physical phenomena.

2. How is frequency calculated?

The equation of frequency is calculated by taking the inverse of the period of a periodic event. This means dividing 1 by the amount of time it takes for one complete cycle or oscillation to occur. The resulting value is the frequency in units of hertz (Hz).

3. What is the relationship between frequency and wavelength?

Frequency and wavelength are inversely proportional to each other. This means that as the frequency of a wave increases, the wavelength decreases and vice versa. This relationship is described by the equation: frequency = speed of light / wavelength.

4. How is frequency measured?

Frequency is measured using a device called a frequency counter. This device counts the number of oscillations or cycles of a periodic event within a specific time frame, typically in seconds. The resulting value is then converted to the appropriate frequency unit (Hz, kHz, MHz, etc.).

5. How is the equation of frequency used in practical applications?

The equation of frequency is used in various fields of science and technology, such as physics, engineering, and telecommunications. It helps to describe and analyze the periodic behavior of waves, electricity, and other phenomena. It is also used in the design and development of devices and systems that rely on precise frequency measurements, such as radios, satellites, and medical equipment.
