standard unit -- Pascal

        Newton per square meter
 

What is the orientation of the object while sitting on the surface
 
 

Fluid Pressure
    Fluid – substance that flows
            Gas
            Liquid
    All of the forces exerted by the individual molecules in a fluid
     add together to make up the pressure exerted by the fluid

            watch the video, why did the soda can get crushed?

Pascal’s Principle
        When force is applied to a confined fluid,
        an increase in pressure is transmitted equally to all parts of the fluid

        Hydraulics

                What happens to the pistons as the force is applied?

            hydraulic lifts
                

                    a small force applied to a small area transmits the pressure to a larger area, creates a larger force.
                        a small "input" with a large "output"
 
 

            Pascal’s Principle in Nature
                     starfish use a complex hydraulic system to move around or cling to rocks
               If you've ever tried to pry a Starfish off a rock, you know how effective its hydraulic system really is.
