Formula for the velocity of the centripetal force

Click For Summary

Homework Help Overview

The discussion revolves around understanding the relationship between centripetal force and velocity in circular motion, specifically focusing on a scenario involving a radius of 100 cm and a period of 0.98 seconds for one revolution.

Discussion Character

  • Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • The original poster attempts to find a formula for the velocity related to centripetal force, while some participants clarify the terminology and suggest that the focus should be on tangential velocity in circular motion.

Discussion Status

Participants are exploring the definitions and relationships between centripetal force and velocity. Some guidance has been offered regarding the correct interpretation of the terms involved, and a formula for centripetal force has been provided, although there is no explicit consensus on the original poster's question.

Contextual Notes

There is a noted confusion regarding the terminology of "velocity of a centripetal force," with participants questioning the assumptions behind the original poster's phrasing and intent.

Hi, can anyone please tell me the fomular for the velocity of a centripetal force with the radius of 100 cm, with one revolution revolting in 0.98 seconds?

Here are the formulas you will need to solve the problem:
v = rw
w = 2pi/T

By the way, the "velocity of a centripetal force" does not have much meaning. Force is a vector; it doesn't have velocity. You might as well have asked what the mass of the force was, or the radius of the force. I think you meant to say that you are trying to find the tangential velocity of an object undergoing circular motion due to a centripetal force.
 


Thanks for you're help, anyway i have another question. What is the formula for centripetal force?, our physics teacher gave us a practical to do but he forgot to give us a note on centripetal force.
 


It's F = (mv^2)/r, directed radially inward.
