Bernoulli’s Principle Chapter 11 Section 4

Fluid Motion A fluid naturally flows from an area of high pressure to an area of low pressure. In the 1700s, Swiss scientist Daniel Bernoulli discovers that the pressure of a moving fluid is different than the pressure of a fluid at rest.

Bernoulli’s Principle Bernoulli’s principle states that as the speed of a moving fluid increases, the pressure within the fluid decreases.

Objects in Flight The wing of an airplane is designed to produce lift. Lift is an upward force.
