  1. WELCOME TOPhysics 1401:A1 & A3 Mr. Kris Byboth

  2. Syllabus • The course syllabus can be found on the web at http://www.blinn.edu/brazos/natscience/kbyboth/

  3. Keys To Success • Don’t get behind • Ask a question every time something is unclear!!! • Write a formal solution to every problem (learn how to approach problems) • Work more problems (you cannot memorize physics) • Form study groups

  4. What is Physics? • Physics is the study of the laws of nature. • It is the attempt to understand, model, and predict the behavior of the world around us. • This course will emphasize application of mathematical models to physical situations.

  5. Units • Each measurement requires some predefined unit of measure. • Units will often help you identify what variables are being given in a problem.

  6. SI Units Length meter (m) – The distance traveled by light in vacuum in 1/299,792,458 seconds Mass kilogram (kg) – The mass of a specific platinum-iridium cylinder Time second (s) – The period of 9,192,631,770 oscillations the radiation from a cesium-133 atom

  7. Conversions • Converting between units is just multiplying by one. • 7.4ft = ?in • The conversion factor is 1ft = 12 in

  8. Conversion factors to know • 1ft = 12 in • 1in = 2.54cm • 1yd = 3ft • 1mi = 5280ft = 1609m • 1m = 3.281ft • 1hr = 60min = 3600s • 1m = 100cm = 1000mm • 1km = 1000m

  9. Unit Prefixes table 1-4 pg 5 Prefix Abbreviation Conversion • mega M 106 • kilo k 103 • centi c 10-2 • milli m 10-3 • micro μ 10-6 • nano n 10-9 • pico p 10-12 • Read as 1 (Prefix) = Conversion (unit) • 1kilometer = 103 m = 1000m • 1cm = 10-2 m = 0.01m

  10. Conversion Practice • 10,000ft = ? mi • 1.89mi • 4.5yd = ? cm • 411.48cm • 45m2 = ? cm2 • 450000cm2 • 55mi/hr = ? m/s • 24.59m/s

  11. Round Off Errors • Round off errors are deviations of a solution (usually but not always small) from the actual solution due to rounding intermediate calculations in route to the final solution. • If possible reduce all problems to an algebraic solution then calculate a numeric answer.
