6 Multiple choice questions

  1. This comes from the air lifting the plane.
  2. Any material that can flow and take shape of its container. This includes- Liquids and gases.
  3. All fluids exert pressure. Pressure is created by the particles in a fluid pushing against each other and the sides of whatever container they are in. Fluids exert pressure equally in all directions.
  4. An amount of force exerted on a given area.
  5. This= Force divided by Area. Square meter/ n divided by meter2
  6. The metric (SI) unit for pressure. Abbreviation: Pa.

6 True/False questions

  1. Force, Pressure, and AreaBecause pressure increases with depth, the pressure on the bottom of the object is greater that n the pressure on the top. Therefore, there is a net upward force on the object.

          

  2. PressurePressure only depends on the depth of the fluid, not the total amount present.

          

  3. ThrustThis comes from air resistance.

          

  4. Pascal's principleAs the speed of a moving fluid increases, its pressure decreases. A frisbee works like this, and a boomerang to.

          

  5. Fluid behaviorAny material that can flow and take shape of its container. This includes- Liquids and gases.

          

  6. Archimedes' PrincipleA change in pressure at any point in an enclosed fluid will be transmitted equally to all parts of that fluid. Uses and examples: brakes, power, lifters, etc. Liquids are best used in hydraulic devices because they cannot be compressed into smaller spaces like gases can.
