Document Summary

Physics- fundamental aspects of matter and motion through space. All of physics depend on measurements (temp, time, mass) Measurement: number and unit never exact counted quantities are exact uncertainty is the possible error in a measurement uncertainty of a measured quantity is indicated by number of significant figures. Significant digits include digits known for certain & estimated digits. Significant digits tell us about instrument used for measurement. Ex/ 56. 001 cm are all sig/ digits. i) ii) 3 bc zeros between sig figs are significant. 4 bc 0"s after sig figs are significant. 2 bc 2 sig figs when scientific notation.
