Hey--
I'm writing up a physics lab report on centripetal force; at the moment I've hit a problem with the velocity squared vs. radius graph. The graph *should* show a root curve (v^2 = Fr/m) but all of the regression utilities I've used churn out an exponential curve. Here are the four points I have:
Radius (m)
0.25
0.5
0.75
1
Velocity Squared (m^2/s^2)
43.52321446
105.3350938
174.1416131
227.3593065
Adding to the enigma is the fact that my velocity vs. radius graph, which should also show a root curve, actually DID. All I did to the velocities was square them for the v squared graph.
Any idea what's going on?
Thanks!
Pat
