Fluids and Motion
Based on Bernoulli’s Principal:
Pressure in a fluid decreases as the fluid’s velocity increases.
Lift: Upward force on object in fluid
Thrust: Pushing force exerted by engine
Drag: Opposes motion of airplane (friction)
Small Wing = Less lift / need large thrust
Large wing: More lift / need less thrust
Air travels fast over top of wing and slower over bottom of wing
Slow fluid: high pressure
Fast Fluid: Low Pressure
Fluids flow from high to low pressure causing the wing to lift
Upward Lift
High Pressure Here
