6 Multiple choice questions

  1. An amount of force exerted on a given area.
  2. The buoyant force on an object in a fluid is an upward force equal to the weight of the volume of the fluid that the object displace- displace means " take the place of"
  3. This= Force divided by Area. Square meter/ n divided by meter2
  4. The upward force that fluids exert on all matter. Buoyant Force is caused by differences in fluid pressure.
  5. Because 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.
  6. Any material that can flow and take shape of its container. This includes- Liquids and gases.

6 True/False questions

  1. LiftThis comes from the air lifting the plane.

          

  2. Plane's and their pressureThe wing shape on a plane os what causes different speed of air, which affects pressure. The air that foes over the wing must travel faster than the wing to meet up at the end. This creates less pressure above the wing compared to below which creates lift.

          

  3. FluidsAny material that can flow and take shape of its container. This includes- Liquids and gases.

          

  4. DensityThe amount of matter in a certain volume. Water is more dense than air; and therefore, it exerts more pressure.

          

  5. Fluid behaviorWhy does liquid travel up a straw when you drink from it? Because as pressure decreases the water pressure increases.

          

  6. DragThis comes from air resistance.
