Document Summary

Sound vibration of the sound source. Sound is a physical event; need a base knowledge in physics. Today"s (cid:272)lass (cid:449)ill (cid:271)e fo(cid:272)used on basic physics. Three fundamental physical quantities (cid:862)easiest (cid:449)eight loss (cid:396)egi(cid:373)e is to go to the (cid:373)oo(cid:374). (cid:863) Mass- the amount of matter that is present. Units for mass are grams(g) and kilograms(kg) Weight is related to gravity; mass is not. Units for length are meter (m), kilometer (km), feet, inch, yard. 1 second = the time needed for light to travel 300,000km. Second is the standard unit for time (s).
