oh, we didn't learn any of that, only ever used S.D. in biology as uncertainty. My physics teacher said I could use ± 0.01 s for each trial, and keep this uncertainty for the average in time trials too; would that be fine you think?

Homework Statement [/B] So basically I am calculating the terminal velocity for a small sphere falling in a measuring cylinder filled with glycerine. The distance traveled is 20 cm (0.20 m), and I have conducted 3 trials for each temperature. I have measured the displacement of the ball using...

Thanks again! Btw, one more question. If I plot 1/T vs. log viscosity I get a linear graph. Doing some research I found that they are related in a somewhat Arrhenius type relation, where the slope when graphed = Ea / R. However, what does this 'Ea' mean? In chemistry we learned that it was the...

Thanks! Do you think glycerin is a good viscous liquid to test this with?

Oh yeah and also, it's linear if I plot 1/T versus log viscosity! But I was wondering, why is this? Since temp and visc. are inversely proportional, wouldn't 1/T vs plain viscosity linearise it? Are there any justifications I can make of why log viscosity vs. 1/T gives me a linear graph? Also...

I thought about actually conducting the experiment myself at home or quickly at school just to see if it does reach terminal velocity using a slowmotion video capture device and seeing how long it takes to travel 0.2 cm (for instance) by splitting the total distance (20 cm) in 10 parts and...

Hey all, I'm new to the forums and had a quick question: (please tell me if this is the wrong topic under which I posted, please move it if needed! @mods) I am doing a lab report investigating the effect of temperature (˚C) on the dynamic viscosity (Pa s) of glycerin. I am timing the time it...
