Measurement Techniques in Physics Lab

The video introduces the first physics lab focused on measurements and uncertainty. It covers the use of various measurement tools such as meter sticks, rulers, vernier calipers, and double pan balances. The video explains how to determine uncertainty and significant figures in measurements. It also demonstrates the use of Logger Pro for graphing data and analyzing relationships between variables, specifically focusing on the relationship between the diameter and circumference of circular objects.
