    • How does Bernoulli's Principle explain the operation of siphons?
      Faster fluid has lower pressure
    • What does Archimedes' Principle state about the upward buoyant force on a submerged object?

    • Steps to explain how Bernoulli's Principle creates lift in an airplane wing:
      1️⃣ Air flows faster over the top of the curved wing
      2️⃣ Pressure decreases above the wing
      3️⃣ Higher pressure below the wing
      4️⃣ Upward lift force is created
