Types of PressureTypes of Pressure Air Pressure- The pressure exerted by the atmosphereAir Pressure- The pressure exerted by the atmosphere Gas Pressure- The pressure exerted by gasGas Pressure- The pressure exerted by gas Fluid Pressure- The pressure at some point within a fluid. Such as Fluid Pressure- The pressure at some point within a fluid. Such as
water or air.water or air. Oil Pressure- Pressure that keeps oil on the moving parts of an Oil Pressure- Pressure that keeps oil on the moving parts of an

Equations for PressureEquations for Pressure
Pressure Eqauation: P=Force/Area=F/APressure Eqauation: P=Force/Area=F/A Force=Pressure x AreaForce=Pressure x Area Area= Force/PressureArea= Force/Pressure

Density and PressureDensity and Pressure
Fluids with a greater density will exert a Fluids with a greater density will exert a greater pressuregreater pressure
Pascal’s Principle Pascal’s Principle
A change in pressure at any point in an A change in pressure at any point in an enclosed fluid will be transmitted equally to enclosed fluid will be transmitted equally to all parts of the fluidall parts of the fluid
