12-Sept-2014 Determination of unknown mass.

Measuring the Density of Metal Cylinders

Purpose for this experiment was to learn how to calculate propagated uncertainty.

Here we are measuring the density of 3 metal cylinders. With the use of calipers we measured the diameter and height. Calipers can have an error of (+/-) .01cm. Mass was measured on a scale with error of (+/-) 1g.

density = (4*m)/(h*pi*D^2)

Determination of an unknown mass

My table decided to look at unknown mass #10. 

uncertainty of angle = (+/-) 2 degrees

uncertainty of force = (+/-) .5N

m = .704kg

uncertainty of mass = .9%
