Ask an Explainer

Q:

Why does lift increase as speed increases?

A:

Fast air has low pressure. So when plane's speed increases, the speed of the air over the wing does too. This means that the pressure above the wing drops. Since the air below the wing is moving more slowly, the high pressure there will push up on the wing, and lift it into the air.
