Document Summary
Base units, conversions, significant figures and final and. Physics is the study of the basic particles of matter and their interactions in order to deduce: Engineering is the application of physics to the structure and functioning of materials to advance technology. We can convert in systeme international where the fundamental quantities and units are m, kg and s. 1000m 103 = 1 km 1km x 103 = 1000m (base units) o o o o o. Density of water is 1g/cm3 and 1ml = 1cm (cgs another metric system) To convert units use chain method (1m x 100cm/1m = 100cm) If answers seen wrong, comment about it for bonus marks. Accuracy is how close a value is to real and precision is how reproducible the value is. Error: final answers have x + errorx; x is rounded to number of decimals errorx has. Scientific notation: all digits are significant 1. 9 x 105 -> 190 000.
