hi i'm a new member in this forum and i'm taking physics(University level) grade 12.......in one of our labs about the relationship between centripetal force and radius, we must use a constant centripetal force( we used 2N) and find the frequency in RPM for different radii, and this is what we got:(adsbygoogle = window.adsbygoogle || []).push({});

Fc:2N ( Constant)

Radius: RPM:

0.8 88

0.6 113

0.4 138

0.2 192

then he asked to plot a graph of Fc versus frequency squared.

(Note:also it says after that to draw a line from each point to the origin because Fc for frequency 0Hz is 0)

my question is do we just square the frequency we got in experiment, or is there some kind of a trick he wants us to understand?????

If u could explain this to me please, i'd be very grateful.

THANK YOU.
