2.1.2.1 1. Quantitative Problems 2. Concept Checks
3. Reasoning & Relationship problems
(Identify what important might be "missing"
2.2 Scientific Notation
& Significant Figures
2.2.1 Shorthand of writing
very large and/or small
numbers
2.2.2 Significant Figures
2.2.2.1 1. Nonzero digits ARE
significant 2. Final ending
zeros written to the right of
the decimal ARE significant
3. Decimals that are
placeholders are NOT
significant 4. Zeros written
between digits ARE
significant
2.2.3 Round numbers at the VERY end
2.3 Units Conversions
& Dimensions
2.3.1 Dimensions: basic types of quantites
that can be measured or computed
2.3.1.1 Unit: Standard amount of a dimensional quantity
2.3.1.1.1 EXAMPLES: kg,m,s
2.3.1.2 EXAMPLES: Length, Time, Mass,
Electric Current,
Temperature
2.3.1.3 Dimensional Analysis:
used to check problems
2.3.1.3.1 Use: L for length, T for time, M for mass
2.4 Vectors
2.4.1 Written as an arrow and length mean
magnitude and direction means direction
it would be on a coordinate system
2.4.2 use trig. to find the
sides and/or angle
(cosine and sine)
2.4.3 to add vectors, tip-to-tail so A+B=C
