  1. Physics Skills

  2. Units of Measurement • Metric System primarily used • SI Units • International System of Units (SI) • MKS Units • Base Units: Fundamental units from which all other units can be derived.

  3. MKS or SI Base Units

  4. Derived Units • Derived Units: Units that consist of combinations of base units.

  5. Converting Units • Converting from large to small move the decimal to the right • Converting from small to large move the decimal to the left • Number of decimal places are equal to the difference between the powers of each prefix

  6. Prefixes

  7. SCIENTIFIC NOTATION • Scientific Notation: Representing very small or very large numbers in compact form. • Moving the decimal to the right yields a negative exponent • Moving the decimal to the left yields a positive exponent

  8. Algebra Review • y = xz Solve for x •  x = y/z • When x is multiplied by another variable/number divide both side by that variable/number.

  9. Algebra Review (Cont.) • y = x/z •  x = zy • When x is divided by another variable/number multiply both side by that variable/number.

  10. Algebra Review (Cont.) • y = z/x •  x = z/y • When x is in the denominator first multiply both sides by x, then isolate x by either dividing or multiplying both sides by the other variable/number.

  11. Algebra Review (Cont.) •  x = y2/z • If x is under the radical sign first square both sides, then isolate x by either dividing or multiplying both sides by the other variable/number.

  12. Algebra Review (Cont.) • y = x2/z •  • If x is squared, either take the square-root of both sides, then isolate x by either dividing or multiplying both sides by the other variable/number, or isolate x2 first then take the square-root
