what do you mean by a "continuous theoretical solid line using the formula"? As in a line of best fit?
this is the graph I currently have, which displays my experimental values with an uncertainty of plus/minus 0.1 m/s.
Sorry, I do not understand what you mean.
I had to find whether the inner radius of a cylinder affects its velocity when it rolls down an inclined plane. I timed each trial and I found there was a negative correlation. The formula I provided is a derived equation. I found the velocity for each inner radii value based on this formula...
I have tried using the y = ab/c uncertainty formula
for the (ro^2 + ri^2)/4(ro^2) but not sure where to go from there
Im unsure how to combine uncertainties
