09Under suitable flow conditions, this principle links higher fluid speed with lower pressure along a streamline.RECALL
Bernoulli's Principle
Bernoulli's principle links a fluid's speed to its pressure, helping explain how airflow generates lift on a wing.

Levers
A lever multiplies force around a pivot point, the principle at work in a balanced seesaw.

Pulleys
A pulley redirects a pulling force, letting a rope raise a flag by pulling down instead of up.
