## Circular motion question

Hi. I would like to know if someone could help me out in this pre-lab homework.

Is only about theoretical x vs y graphics corelating frequency with radius, mass and centripetal force.

I have thhis equation, Im not sure if there are others that should be used, tough.

Cf=4($$\pi^2$$)mr($$f^2$$)

For the graphic f vs Cf Do I take in count radius and mass constant? Or do I just need antoher equation? Could you give it please?

For the graphic f vs r Do I take in count centripetal force and mass constant? Or is it with other equation?

For the f vs m graphic. Do I take in count radius and centripetal constant?

Thank you a lot.

 Blog Entries: 3 Recognitions: Gold Member Welcome to the forum. A useful technique is to replace the variable in the equation by x and y. So the Cf vs f graph is x=A.m.r.y^2 ( A=4.pi^2) and the f vs Cf is y=A.m.r.x^2, and so on. For anything that is not x or y, select a value that suits you. The shape of the graph will not be affected by your choice, only the lengths of the axes.
