Part 2: Accuracy vs Precision The objective of this exercise is to understand the difference between precision and accuracy in a series of measurements. Equipment Virtual Bull's Eye (2 sheets with Carbon paper in between) Procedure Part A )Imagine that you lace the Bull's Eye on the floor, and then t drop a small ball from a 2-meter height (say, extending your arm above your head), aiming at the center of the target 2) The ball, hitting the carbon paper,...
