You friend Judy asks you to explain how come planes can fly.?Describe using Bernoulli's principle how heavy object, like plane are able to fly.make sure to include the following words.?

Planes are able to fly due to Bernoulli's principle, which states that as the speed of a fluid (such as air) increases, its pressure decreases. This principle explains how planes are able to generate lift and stay airborne.

When a plane's wings move through the air, the shape of the wing causes the air above it to move faster than the air below it. This creates a pressure difference, with lower pressure above the wing and higher pressure below the wing. This pressure difference creates lift, which allows the plane to overcome gravity and stay in the air.

In addition to Bernoulli's principle, planes also use engines to generate thrust, which propels the plane forward. This forward motion, combined with the lift generated by the wings, allows the plane to take off and stay in the air.

So, in summary, planes are able to fly because of the combination of Bernoulli's principle creating lift and engines generating thrust. This allows heavy objects like planes to overcome gravity and stay airborne.

Bernoulli's Principle and the Flight of Planes

Dear Judy,

In response to your question about how heavy objects like planes can fly, let me explain it using Bernoulli's principle.

Bernoulli's principle states that as the velocity of a fluid (such as air) increases, its pressure decreases. This principle plays a crucial role in the flight of planes.

A plane has wings designed to create a difference in airspeed between the upper and lower surfaces. The shape of the wings causes the air to flow faster over the top surface than over the bottom surface. According to Bernoulli's principle, this difference in airspeed creates a pressure difference, with lower pressure on the top surface and higher pressure on the bottom surface.

This pressure difference generates an upward force known as lift. Lift is the force that opposes the weight of the plane, allowing it to stay in the air. The greater the difference in airspeed between the upper and lower wing surfaces, the greater the lift generated.

In addition to lift, planes also rely on thrust to move forward. Thrust is generated by the plane's engines, which push air backward. The reaction to this backward push provides the plane with forward motion.

Combining lift and thrust, planes are able to overcome their own weight and fly. The careful design of wings, which apply Bernoulli's principle, enables these heavy objects to soar through the air.

Hope this explanation helps you understand the remarkable phenomenon of flight!
