Uniform circular motion equation

Click For Summary
SUMMARY

The discussion centers on deriving an equation for frequency (ω) in uniform circular motion based on three proportional relationships: tension (T) is proportional to frequency, radius (r) is inversely proportional to frequency, and mass (m) is inversely proportional to frequency. Participants suggest that the relationships can be combined into a single equation, with ω expressed in terms of T, r, and m. The relationships are summarized as ω = aT, ω = b/r, and ω = c/m, where constants a, b, and c depend on the respective variables.

PREREQUISITES
  • Understanding of uniform circular motion principles
  • Familiarity with the concepts of tension, radius, and mass
  • Basic knowledge of proportional relationships in physics
  • Ability to manipulate equations and solve for variables
NEXT STEPS
  • Research the derivation of the centripetal force equation in circular motion
  • Learn how to combine multiple proportional relationships into a single equation
  • Study the relationship between angular velocity and linear velocity
  • Explore the effects of mass and radius on frequency in circular motion
USEFUL FOR

Students studying physics, particularly those focusing on mechanics and circular motion, as well as educators seeking to clarify concepts related to tension, mass, and frequency in uniform circular motion.

ok so we did a lab. By looking at the graph, we determined that

force of tension is proportional to frequency of revolution
radius is indirectly proportional to the frequency of revolution
mass is indirectly proportional to the frequency of revolution

the next part of the question is

"combine the three results to obtain a equation for the frequency in terms of the tension, the radians, and the mass."

My group and I have no clue how to combine the 3 relationships to form one equation for frequency. Please help me out if you can please

Hello HelloMotto! :smile:

(i think you mean "inversely proportional" :wink:)

ω = aT, where a depends on r and m

ω = b/r, where b depends on T and m

ω = c/m, where c depends on T and r

so ω = … ? :smile:

you don't understand what? :confused:

T is tension, r is radius, m is mass, ω is frequency,

a is a function of r and m, but is a constant if r and m are fixed
