Uncertainties - Help!
I am processing the data in my pulley experiment and I have a doubt.
I am measuring the efficiency, thus, I measured the work I inputed in the system. For when the mass being lifted by me was moved by 0.05m, I exerted a 1.4 N force and I had to exert that force for 0.275, 0.28, 0.285. (Those are my repeats)
My question is: The uncertainty for the distance I moved the force would be the smallest degree of accuracy in my ruler or half the range?

What are the units for the duration of the effort? seconds, minutes, hours, fortnights?
