# what is the physical significance of k/m?

this question is related to uniform circular motion and centripetal force..

I don`t understand the question,and what are the points should I include while answering this question.Help me please!

In the above poster's description, k/m only has significance in a situation which has nothing to do with uniform circular motion...ok, maybe a little, because they are both situations of periodic motion.

k/m means the stiffness constant of a spring (k) divided by the mass (m) of the attached object. The cycles per second frequency in such a situation is found by f = sqrt(k/m)/(2*Pi).

As for uniform circular motion...have you tried just posting an example from your homework or textbook verbatim...and then post what parts you don't understand? That works for most people.

Also, in uniform circular motion...remove the terms "centripetal force", "centrifugal force", and "Coriolis force" all from your vocabulary. They are the most unnecessary and confusing concepts in introductory physics. Use the word "centripetal" ONLY as an adjective with the word "acceleration".
