Unscramble the Blue Letters


One especially pervasive false dirpoticsen of lift is the “Longer Path” or “Equal Transit Time” explanation. It states that air molecules traveling over the top of a ceuvrd wing cover a longer distance than those traveling underneath. For the air meleolcus above to reach the wing’s trailing edge in the same instance as those that split off and went below, air must travel faster above, cintreag a poekct of lower pressure that lifts the plane. This explanation has been thoroughly debunked. Air molecules floating above and below the wing don't need to meet back up. In rlaiety, the air tlivnreag above reaches the wing’s trailing edge much faster than the air beneath.

Original Text


One especially pervasive false description of lift is the “Longer Path” or “Equal Transit Time” explanation. It states that air molecules traveling over the top of a curved wing cover a longer distance than those traveling underneath. For the air molecules above to reach the wing’s trailing edge in the same instance as those that split off and went below, air must travel faster above, creating a pocket of lower pressure that lifts the plane. This explanation has been thoroughly debunked. Air molecules floating above and below the wing don't need to meet back up. In reality, the air traveling above reaches the wing’s trailing edge much faster than the air beneath.
