February 20, 2014 Homework: Finish poster or Paragraph, due tomorrow Friday 2/21 (remember on 8 ½ x 11 in paper) Do Now: -Write down homework -Update TOC: pg 76: Review of Pressure & Elevation/Depth -Glue in metals and Alloys sheet to pg. 70 -Glue in Pressure sheet to top of pg. pg 76 and complete #’s 3,4, &5
Fluid Pressure-Pressure & Depth Water pressure increases as depth increases—the deeper down you go the more pressure there is! http://www.calctool.org/CALC/other/games/depth_press
Air Pressure is Measured with a Barometer Open Textbook to pg. 80
P= Force/Area I Hope I don’t have to Force you into measuring and calculating…don’t worry…. No Pressure! The unit of pressure is a Pascal(Pa): 1 Pa = 1N/m² Force = Newton's (N) Area = cm² or m²
