  1. Bernoulli’s Principle חוקברנולי

  2. Bernoulli’s Principle: • מדען שוויצרי הידוע בעיקר בזכות עבודתו הקושרת בין הלחץ בזורם ומהירותו

  3. Bernoulli’s Principle • Pressure in a moving stream exerts less pressure than the air surrounding the moving stream Quick stream = low air pressure Slow stream = High air pressure

  4. Bernoulli & Flight • Bernoulli’s Principle is what allows birds and planes to fly. • The secret behind flight is ‘under the wings.’

  5. The air on top of the wing must travel a longer • distance than the air below the wing. But, air on • both sides must reach the end of the wing at the • same time. Therefore, the air on top of the wing • traveling faster = less air pressure. Creates Lift AIR

  6. Below is a NASA illustration of what surface pressure is exerted on what surface areas of the wing.
