PPT-Air Pressure

Air molecules are moving constantly They bounce off everything like rubber balls They are bouncing off your body and everything around you right now Each time an air molecule bounces off an object it pushes EXERTS FORCE on that object When billions of air molecules bounce off a surface the force is spread over the area of that surface. Set-Up and Safety. High-Pressure Air Bags. This PowerPoint is intended as a general review of high-pressure air bag set-up and safety practices.. There are various different air bag systems currently used in Snohomish County. Always refer to your departments SOP/SOG’s as well as manufacturers recommendations prior to use.. Air molecules are moving constantly! They bounce off everything like rubber balls! They are bouncing off your body and everything around you right now!. Each time an air molecule bounces off an object, it pushes (EXERTS FORCE) on that object. When billions of air molecules bounce off a surface, the force is spread over the area of that surface.. Defined as the force exerted on you by the weight of tiny air . particles . in . the atmosphere per unit area.. Earth’s atmospheric pressure = 14.7 pounds per square inch OR 1 kilogram per square centimeter. PRESSURE. “press” = push on a surface. Pressure = Force/ surface area. P= F/ SA. Unit: . pascal (Pa) =1 N/m. 2. Who exerts more pressure on the ground an . elephant. or a . woman . Key Concepts: What are some of the properties of air?. What instruments are used to measure air pressure?. How does increasing altitude affect air pressure and density?. Key terms:.

The air is made up of molecules.. 2. .. Air molecules are all around us. 3. Like all matter, air molecules have mass.. Vanderbilt Student Volunteers for Science. Training Presentation. Spring 2019. IA. What is the . Atmosphere. ?. Write the following terms on the board: atmosphere, air pressure, vacuum. EVERYONE MUST WEAR GOGGLES!. Earth’s gravitational force. Atmospheric Pressure. As the atmosphere is held down by gravity, it exerts a force upon every surface (pressure = force per unit area). At sea level the force is the weight of 1 kg of air that lies above each square centimeter of the surface (around 15 lbs per in. The horizontal distribution of air pressure on the globe is studied on the basis of Isobars. If we look at the globe then it appears that there is certain definite system of high and low pressure.. If, for generalization, the globe is considered to be homogeneous (either of land or water), then there should be regular and systematic zonal distribution of high and low pressure but the regularity of pressure belts is distributed due to unequal distribution of land and water on the globe. .
