- An amount of force exerted on a given area.
- The metric (SI) unit for pressure. Abbreviation: Pa.
- Pressure caused by the weight of the atmosphere. Earth's atmosphere is held in place by gravity. Although we don't feel this pressure because the fluids in our body exert an equal outward pressure. The closer you are to Earth's surface you are, the greater the pressure because you are "deep" in the atmosphere.
- This comes from the air lifting the plane.
- 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.
- The 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.
6 True/False questions
Buoyant force → This= Force divided by Area. Square meter/ n divided by meter2
Fluid behavior → Any material that can flow and take shape of its container. This includes- Liquids and gases.
Pressure → 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.
Force, Pressure, and Area → This= Force divided by Area. Square meter/ n divided by meter2
Drag → This comes from the air lifting the plane.
Archimedes' Principle → 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"
