  1. Significant Figures & Scientific Notation Physics

  2. Significant Figures Indicate accuracy of measurements Several rules for # of significant figures.. • Non-zero digits are always significant. • Any zeros between two significant digits are significant. • A final zero or trailing zeros in the decimal portion ONLY are significant.

  3. Accuracy vs. Precision Accurate? Precise? Both? Neither?

  9. Scientific Notation • Common technique used to express very large or very small numbers. • Large #: Mean distance from Earth to Sun • 93,000,000 miles • Small #: Mean distance across a helium atom • 0.00000000000008699 miles • Maintain accuracy! (Keep same # of significant figures) • Only 1 significant figure to the left of the decimal point.
