Introduction to Measurements 1. Measure the diameter of a lacrosse ball with a ruler. 6.4 cm ± .1 cm 2. Measure the diameter of a lacrosse ball using a Vernier caliper. Compare this measurement to your result from Exercise 1. 6.335 cm ± .005 cm When measuring the diameter of the lacrosse ball with the ruler, instrumental uncertainty was present on the millimeter scale. However, when measuring the diameter of the same ball with the Vernier caliper, uncertainty was only found at .005 cm. Because of this, it can be deduced that the Vernier caliper is a more precise and accurate instrument to measure with. 3.Measure the average diameter of a squishy ball. How does the uncertainty you assign to this measurement compare to what you did in Exercise 2?
