Unformatted text preview: function that involves both the sum and product of measured quantities h ( a,b,c ) = a b + c can be determined by rst nding the uncertainty in the individual components, i.e. nd g ( a,b ) for g ( a,b ) = a b using formula (2) and then rewrite h as h ( g,c ) = g + c and apply formula (1). Interpretation of results with uncertainty Often times the purpose of lab experiments is to experimentally conrm the value of a known quantity (such as the acceleration due to gravity) or to compare a quantity that is measured in two dierent ways (for example the speed a bullet leaves a gun based on a measurement of its trajectory as well as a measurement of its ability to displace a large mass). When comparing two quantities that each have uncertainty (if one of the quantities 98...
