- This comes from the air lifting the plane.
- Any material that can flow and take shape of its container. This includes- Liquids and gases.
- 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.
- An amount of force exerted on a given area.
- This= Force divided by Area. Square meter/ n divided by meter2
- The metric (SI) unit for pressure. Abbreviation: Pa.
6 True/False questions
Force, Pressure, and Area → 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.
Pressure → Pressure only depends on the depth of the fluid, not the total amount present.
Thrust → This comes from air resistance.
Pascal's principle → As the speed of a moving fluid increases, its pressure decreases. A frisbee works like this, and a boomerang to.
Fluid behavior → Any material that can flow and take shape of its container. This includes- Liquids and gases.
Archimedes' Principle → A 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.
