DISCUSSION: Compare the value you just obtained from the dynamic measurement to that of the measuring tape. Do the values agree? The value obtained using the tape and the measuring tape were very precise in comparison to the ones obtained using the iOlab. The measuring tape value was measured to be 30.00 cm with an uncertainty of ± 0.05 cm, resulting in a range from 29.95 cm to 30.05 cm. Similarly, the dynamic value acquired was discovered to be 30.00 cm with an uncertainty of ± 0.02 cm (or 0.300 ± 0.002 m), leading to a range of 29.98 cm to 30.02 cm. As all the values for each measurement fall within each other's acceptable ranges, it is appropriate to conclude that the values agree. What is A? What is B? What are the units of A and B? Does your hand drawn line of best fit agree with the fit from iOLab? In the equation Y= Ax + b, which forms a straight line, A is the slope of the line, and B is the y-intercept (when x= 0). As seen in figure 4, the x axis of the graph is the number of banana cases used, and the y axis is the number of strawberry cases used. In the function’s equation, A is unitless, as it only describes the slope of the function, however B (when 0 cases of bananas have been used) has the unit: number of strawberry cases used. The hand draw line resulted in a slope of 2.5, while the iOlab slope was 4.5 ± 0.8 with a range of 3.7 to 5.3. The hand fitted slope for the values on the graph do not agree with the slope fit from iOlab, as 2.5 does not fall into the acceptable range found using iOlab. In contrast, the hand-drawn y-intercept had a value of 5.1, and the iOlab obtained a value of 6 ± 5 with a range of 1 to 11. The value of the y-intercept in the hand-drawn line falls within the acceptable range of the value acquired using iOlab. Therefore, it is possible to conclude that the values for the hand drawn y-intercept and the iOlab intercept agree.
