1. Fluids and Motion Based on Bernoulli’s Principal: Pressure in a fluid decreases as the fluid’s velocity increases.

3. Lift: Upward force on object in fluid Thrust: Pushing force exerted by engine Drag: Opposes motion of airplane (friction)

4. 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

5. Fluids flow from high to low pressure causing the wing to lift Upward Lift

6. High Pressure Here
