Science and Scientific Method

• Science
• Physics is the study of the material world.
• It is a search for patterns, or rules, for the
  behavior of objects in the Universe.
• This search is both temporal and spatial.
• Scientific Method
• A World View
• In physics, the world view is a shared set of
  ideas that represents the current explanations of
  how the material world operates.
• The physics world view is a dynamic one.

Units and Measurements

• Physics is an experimental science which means we
  take measurements. Most of the measurements we
  will take will require the proper units. The
  units are classified within a measurement system.
• Measurement Systems - there are two that are
  currently being used in the world.
• International System of Measurements - SI
• Used by virtually all countries in the world,
  except the USA. Originated by the French in late
  1700s and is based on increments of 10. SI uses
  prefixes to indicate a larger or smaller
  quantity.
• American (English) System
• Developed primarily by the English over a period
  of many years. This system uses units that are
  regular increments of each other.

Units and Measurements II

• Fundamental Measurements and Units
• Metric American
• Length Meter Foot
• Mass Kilogram Pound
• Time Second Second
• Temperature C - Celsius F - Fahrenheit
• Others
• Derived Measurements and Units
• Speed m/s mph
• Units are in length per unit time (L/T)
• Force Newton (N) Pound (lb)
• Units are in lengthmass per unit time squared
  (LM/T2)
• Energy Nm J ft - lb
• Units are in lengthlengthmass per unit time
  squared (L2M/T2)

9
Units and Measurements III

• Unit Conversion and Dimensional Analysis
• Unit Conversion - see handout
• Examples change 88 ft/s to mi/hr
• Dimensional Analysis
• Units of momentum are m kg/s. This means that
  if you solve a formula for momentum, the answer
  has to have units of m kg/s. Notice also that
  each term of the equation has to have units of m
  kg/s or the equivalent.
