SUMMARY
The forum discussion centers on a circular motion experiment where the user measured the time for one revolution of a rubber bung on a string, varying the radius for each trial. The user successfully derived velocity and plotted Velocity^2 against Radius, resulting in a linear line of best fit. To obtain the formula for acceleration, a = V^2/r, the user needs to calculate the slope of the fit line from their graph. This slope directly correlates to the acceleration in the context of circular motion.
