Faster moving fluid creates lower static pressure
Bernoulli's principle explains how pressure drops when fluid or air velocity increases
According to the law of conservation of energy in fluid dynamics, an increase in fluid speed occurs simultaneously with a decrease in static pressure. Aircraft wings exploit this principle by shaping airfoils so that air moves faster over the curved top surface. The resulting pressure imbalance between top and bottom produces aerodynamic lift.

Faster moving fluid creates lower static pressure: the short answers
- Where does this come from, and can I check it?
- Bernoulli's principle explains how pressure drops when fluid or air velocity increases. The figure is taken from NASA Science, which is linked in full on this page. Every fact on Mondo Knows names its source rather than repeating an unsourced claim.
- Is this really a science fact?
- Yes. It sits on the Science shelf, one of 1,090 sourced facts grouped into space, animals, the human body, history, science and more. Category pages collect every fact in the same field.
- What else can I read about it?
- The links under the fact point to a quiz, game, puzzle or calculator on the same subject, and the shelf below shows related facts. The wording here is original, and quoted phrases are marked as quotations.
