|---|---|---|---|---|---|
| Pressure | The force exerted on a surface divided by the total area over which the force is exerted
🗑
|
||||
| Archimedes' Principle | the rule that the buoyant force acting on a submerged is equal to the weight of the volume of fluid displaced by the object
🗑
|
||||
| Density | The Ratio of the mass of a substance to its volume
🗑
|
||||
| Pascal (The Unit Measure) | A unit of pressure equal to 1 newton per square meter
🗑
|
||||
| Fluid | A material that can easily flow
🗑
|
||||
| Buoyant Force (Buoyancy) | The upward force exerted by a fluid on a submerged object
🗑
|
||||
| 4 Forces on airplanes | Lift, Drag, Thrust, and weight
🗑
|
||||
| Pascals Principle | The rule that when force is applied to a confined fluid, the change in pressure is transmitted equally to all parts of the fluid
🗑
|
||||
| Bernoulli's Principle | the rule that the faster a fluid moves, the less pressure the fluid exerts
🗑
|
||||
| Hydraulic System (Definition, How it works) | A hydraulic system multiplies force by applying the force to a small surface area. The increase in pressure is transmitted to another part of the confined fluid, which pushes on the larger surface area
🗑
|
||||
| How does pressure change with elevation? With Depth? | The Deeper You got the more pressure there is from the water pressure above you
🗑
|
||||
| Unit of measure for mass | Grams (g)
🗑
|
||||
| Unit of Measure for force | Newtons (N)
🗑
|
||||
| Unit of measure for Pressure (there are three) | Pascals (P), N/m2, kg/m
🗑
|
||||
| How does Lift Work? | There's a difference at the bottom and top of the wing, the pressure above the wing has less pressure then the pressure below it making it lift
🗑
|
||||
| How do Density and buoyancy determine if an object sinks or floats? | depending on the density of the object the object will sink or float if there's a light density buoyancy will lift it up
🗑
|
||||
| Unit of measure for area | Centimeters (cm)
🗑
|
||||
| Unit of measure for volume | Liter (l)
🗑
|
||||
| Density of Water | one gram per milliliter
🗑
|
||||
| Unit of measure for density | Mass (m)
🗑
|
||||
| Unit of Measure for Buoyancy | Newtons (N)
🗑
|
||||
| Formula for Area | Length x Width
🗑
|
||||
| Formula for Velocity | Velocity = Distance/Time
🗑
|
||||
| Formula for Force (and weight) | Force = m x a
🗑
|
||||
| Formula for Density | d = m/v (Density = Mass/Volume)
🗑
|
||||
| Formula for Pressure | Pressure = Force/ Area ( p = f/A)
🗑
