Why are airplane wings teardrop shaped?
Airplane wings are often curved on the top and flat on the bottom, which makes them look teardrop shaped! This is because of Bernoulli's Principle. Bernoulli's Principle states that faster moving air has lower air pressure and slower moving air has higher air pressure. You can click here to find out more about why! Due to the curve on top of the wing, air is moving faster on top of the wing then on bottom. This means, as airplanes gain speed, the air on bottom will have higher air pressure and push the wing up, giving the plane lift.
