Hello there,
Im currently stuck working out which way to go around calculating uncertainty in finding an experimental value of g.
Just a standard ball drop experiment where the period was recorded for 10, 0.1m increments
Using kinematic equations to find the acceleration due to gravity.
My question is... would it be correct to take the mean of the values of g, and then the standard deviation of the values around that mean to give an "uncertainty"?
Or, should i propogate the error associated with the variables i.e g=f(velocity,time)?
My apologies if this is not the appropriate place to post or im making no sense, I'm currently undertaking a foundation year in engineering having been out of school for 10 years and rapidly trying to get up to speed.
Thanks in advance for any assistance,
T.
