Question regarding Centripetal Acceleration

Click For Summary

Discussion Overview

The discussion revolves around the calculation of centripetal acceleration using two different formulas. Participants explore the accuracy of the results obtained from each formula and the factors influencing measurement accuracy in a lab report context.

Discussion Character

  • Homework-related, Technical explanation

Main Points Raised

  • One participant presents two formulas for calculating centripetal acceleration and seeks help in determining which formula yields a more accurate value.
  • Another participant suggests that the formulas should yield the same accuracy, emphasizing the importance of measurement precision.
  • A participant shares specific results obtained from both formulas, noting that the values are very close.
  • Another participant questions the measurements taken, asking for details on how they were made and the associated measurement errors to assess which formula might yield a better answer.

Areas of Agreement / Disagreement

Participants do not reach a consensus on which formula is more accurate, as the discussion highlights the role of measurement accuracy and error without resolving the question of formula preference.

Contextual Notes

Limitations include potential measurement errors and the need for clarity on how measurements were obtained, which may affect the assessment of accuracy for each formula.

Hi I'm doing a lab report on centripetal acceleration and we are asked to find the centripetal acceleration using 2 formulas.
(1)Acceleration Centripetal=Force Centripetal/Mass

(2)Acceleration Centripetal=Velocity^2/Radius

I get answers that are very close but I also have to answer the question (Which value of Acceleration Centripetal would be considered more accurate? ie: which formula would be more accurate?)

hope someone can help me out here. thanks

The formulas should yield the same "accuracy". The difference will be in your ability to measure. Which of your measurements are the most accurate?
 
I get answers that are very very close. .625 for the first formula and .631 with the second formula
 
What measurements did you make? How did you make them? What are the measurement errors?

You need to consider the answers to these questions in order to determine which of the given forumlas yield the best answer.
