Presentation Transcript

Section 1 pressure
Section 1 - Pressure

  • Pressure - equal to the force exerted on a surface divided by the total area over which the force is exerted.

  • Pressure = force/area

  • pressure units = pascal

  • increase surface area, decrease pressure

  • ice skates

  • fluid - substance which can easily flow

Chapter 11


  • All of the forces exerted by the individual molecules in a fluid add together to make up the pressure exerted by the fluid.

  • Balanced pressure - air pressure

  • pressure at a given level in a fluid is the same in all directions

  • air pressure decreases as elevation increases

  • water pressure increases as depth increases

Section 2 transmitting pressure in a fluid
Section 2 - Transmitting Pressure in a Fluid fluid add together to make up the pressure exerted by the fluid.

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

Chapter 11


Hydraulic system
Hydraulic System fluid add together to make up the pressure exerted by the fluid.

  • Multiplies a force by applying the force to a small surface area.

  • The increase in pressure is then transmitted to another part of the confined fluid, which pushes on a larger surface area.

    • Small force over small area results in a larger force exerted by a larger area at another place.

      • Car brakes, repair shop lift, fire truck ladder

Chapter 11


Section 3 floating and sinking
Section 3 - Floating and Sinking fluid add together to make up the pressure exerted by the fluid.

  • Buoyant force - acts in an upward direction, against the force of gravity.

    • Makes an object feel lighter

  • Archimedes’ principle - the buoyant force on an object is equal to the weight of the fluid displaced by the object

  • floating and sinking - pg. 362

Section 4 applying bernoulli s principle
Section 4 - Applying Bernoulli’s Principle fluid add together to make up the pressure exerted by the fluid.

  • Wright brothers

Chapter 11


Bernoulli s principle
Bernoulli’s principle fluid add together to make up the pressure exerted by the fluid.

  • The pressure exerted by a moving stream of fluid is less than the pressure of the surrounding fluid.

    • Air moves at different speeds above and below objects.

    • Difference in pressure causes lift or downward force

  • wings pg. 367
