Unformatted text preview: σ rms for the resulting curve, and then repeat with diﬀerent values until you found the values that gave the most precise ﬁt, this process can be done quickly by computers, and many software tools exist that will easily do curve ﬁtting. Practice Consider the 4 sets of data shown below for v ( t ) the velocity of an object in freefall with the corresponding linear curve ﬁts. The slope of the best ﬁt line gives the acceleration, and for comparison a dashed line with a slope of-g is shown. Figure 3.1: Example data 21...
