How Can I Prove the Centripetal Force Equation f=mrw^2 Using Experiments?

Click For Summary
SUMMARY

The discussion focuses on proving the centripetal force equation, F = m * r * ω², using experiments with a rotational air table and a handheld whirly string. Participants suggest altering variables such as mass, radius, and angular velocity to observe their effects on force. The importance of comparing experimental measurements with calculated values is emphasized, along with a clarification of the equation's correct form. The conversation highlights the necessity of understanding the relationship between these variables to validate the equation effectively.

PREREQUISITES
  • Understanding of centripetal force concepts
  • Familiarity with rotational motion and angular velocity
  • Experience with experimental physics methods
  • Basic knowledge of calculus for comparing measurements
NEXT STEPS
  • Conduct experiments using a rotational air table to measure centripetal force
  • Learn how to manipulate mass and radius in experiments
  • Explore the relationship between angular velocity and centripetal force
  • Study the application of calculus in analyzing experimental data
USEFUL FOR

Students in physics, educators conducting experiments on rotational dynamics, and anyone interested in validating physical equations through hands-on experimentation.

Hi there, sorry if this is not in the right section, but i have to do an investigation, i have chosen to prove f=mrw2. I will be using a rotational air table, and this the handheld whirly string and mass experiment - sorry to be vague. basically i am not the best physicist so i would very much appreciate if anyone could tell me what variable to change, and the consequent desired effect in my endevour to prove the equation. I am confused. Thanks

Can somebody please tell me how i can prove f=mrw? i have rotational air table and a manual method available. Can i for each experiment change the variables of the equation and show the force change and show how it complies? For instance in one experiment i will alter mass, another i will alter radius and the last angular velocity? Thanks
 
The proof is in the calculus; the lab results compare your measurements with the calculated ones. Better check that equation though before you compare anything. Altering mass, radius, and angular velocity is a very good idea...
 
thanks for your reply, in relation to checking the equation - I am not sure what you mean sorry

In post 2 I guess you made a typo error. F = m(w^2)r.
 
ahh right thanks
