The period of revolution is just based on the time, not the radius of the circle nor the mass of the aircraft, so only the uncertainty of the time needs to be considered.

To get random uncertainty, you'd do the max value minus the min value, all divided by the number of values.

That uncertainty will be for 20 revolutions, so divide by 20 to get the uncertainty for 1 revolution

Hey Ethan I don't have my old notes but I'd say these are just as good. You could give me your email and I could send them to you. Only issues I have with them is in the projectiles example where an object is falling they don't take the acceleration due to gravity as -9.8ms^-2 and they don't use negative displacements for objects hitting the ground from a height, another issue is in the momentum examples they don't use the symbol p to identify momentum they just say momentum=. Other than that they are pretty good, I skimmed through them and they are very similar in layout to the ones I had last year. So inbox me your email and I'll send them to you if you want.
