Physics 2048 Lab Report Lab 2: Measurements and Instrumentation Date Due: September 16, 2010 Introduction and Abstract: The purpose of the experiment was to show how the use of different measuring tools can affect the precision of the data. In this experiment, the experimenters used the linear ruler, vernier caliper, micrometer, and the triple beam balance. The accuracy of the linear ruler was millimeters, the vernier caliper was decimeters, the micrometer was micrometers, and the triple beam balance was grams.

Also in the latter part of the experiment, the experimenters used the pendulum device to calculate the acceleration of gravity at the surface of the Earth. The acceleration of gravity was measures by timing the time taken for the pendulum to swing through one complete oscillation. The acceleration was obtained by the slope of the gravity (4pi 2 /g) and was equal to 10.07mm. Diagram(s) Experimental Procedure: Materials used in this experiment were a linear rule, meter stick, vernier caliper, triple beam balance, pendulum, and stopwatch. The experimenters used the instruments to measure the dimensions of a large rectangle object, large cylinder object, small cylinder object, and a sphere and noted the error of these objects. The latter part of the experiment consisted of calculating the acceleration of gravity. The experimenter measured the length of the string starting at 30 cm, then pulled the sphere back to one side of the pendulum and
