II Measurements and Significant Digits
Connecting Math to Physics Math is the language of physics Using math, physicists are able to describe relationships among the measurements that they make using equations Each measurement is associated with a symbol that is used in physics equations The symbols are called variables Significant Digits
All measured quantities are approximated and have significant digits The number of significant digits indicates the precision of the measurement Precision is a measure of exactness The number of significant digits in a measurement depends on the smallest unit on the measuring tool The digit farthest to the right in a measurement is estimated Example: What is the estimated digit for each of the measuring sticks in the figure below used to measure the length of the rod Using the lower measuring tool, the length is between 9 and 10 cm The measurement would be estimated to the nearest tenth of a centimeter If the length was exactly on the 9cm or 10cm mark, record it as 90 cm or 100 cm Using the upper measuring tool, the length is between 95 and 96 cm The measurement would be estimated to the nearest hundredth of a centimeter If the length was exactly on the 95cm or 96cm mark, record it as 950 cm or 960 cm 0 mm
0 cm
Math Handbook
All nonzero digits in a measurement are significant digits Some zeros are significant and some are not All digits between and including the first nonzero digit from the left through the last digit on the right are significant Use the following rules when determining the number of significant digits 1 2 3 4 Nonzero digits are significant Final zeros after a decimal point are significant Zeros between two significant digits are significant Zeros used only as placeholders are not significant Example: State the number of significant digits in each measurement 50 g has two significant digits 1490 g has four significant digits 00 has one significant digit 30000 mm has five significant digits 506 s has three significant digits 304 s has three significant digits 00060 mm has two significant digits (6 and the last 0) 140 mm has two significant digits (just 1 and 4) Using rules 1 and 2 Using rules 1 and 2 Using rules 2 and 4 Using rules 1, 2, and 3 Using rules 1 and 3 Using rules 1 and 3 Using rules 1, 2, and 4 Using rules 1 and 4 1 State the number of significant digits in each measurement a 1405 m b 250 km c 00034 m d 12007 kg e 58 106 kg f 303 10 There are two cases in which numbers are considered exact, and thus, have an infinite number of significant digits 1 Counting numbers have an infinite number of significant digits 2 Conversion factors have an infinite number of significant digits
