PHYS 211 Chapter Notes - Chapter 1: Significant Figures, Scientific Notation, Decimal Mark
Document Summary
Identify how many significant figures a number has. Use the rules for adding/subtracting/multiplying/dividing numbers with significant figures number of significant figures in the answer. Memorize all of the metric prefixes and what they mean (mega-, kilo-, deci-, centi-, milli-, m. Convert between different units, either metric to metric (such as kilometers to centimeter (miles to kilometers) Recognize the key physics principles that are central to the problem. This requires a conceptual understanding of the laws of physics, how they are applied, and another. Sometimes it just takes a little effort like drawing out the problem. This includes drawing t rewriting the given information, and simply writing down your thoughts on paper. Identify the important relationships among the known and unknown quantities. When dealing with a reasoning and relationship problem, one of these sub steps may invo information or quantities and then estimating reasonable values for these numbers. Solve for the unknown quantities using the relationships found.
