Chapter 3: Scientific Measurement

3.1. Chapter 3: Scientific Measurement. A measurement is a quantity that has both a number and a unit. Measurements are fundamental to the experimental sciences. For that reason, it is important to be able to make measurements and to decide whether a measurement is correct.

Unit 1

Unit 1. Significant Figures. In physics we will be taking measurements and using a lot of numbers for calculations. However, we have to be aware of significant figures (sig figs) because every measurement has a certain degree of uncertainty.
