steel ships can float and even very heavy airplanes can fly, but to achieve flight, you have to exploit the four basic aerodynamic forces: lift, weight, thrust and drag. You can think of them as four arms holding the plane in
For potential flow–no vorticity, or, equivalently, the curl of velocity is everywhere zero–there would be no lift and no drag, so the introduction of vorticity is more than just a pedagogic nicety or a pedantic detail. https://physics.stackexchange.com/questions/46131/does-a-wing-in-a-po...
Having covered the basic physics of flight and the ways in which an airplane uses them to fly, the next obvious step is to consider navigation. How does an airplane turn in the air? How does it rise to a higher altitude or dive back toward the ground? First, let's consider the angle...
So, how does a wing generate lift? To begin to understand lift we must return to high school physics and review Newton's first and third laws. (We will introduce Newton's second law a little later.) Newton's first law statesa body at rest will remain at rest, and a body in motion...
Really? A plane can fly in a purely turbulent state? Perhaps I don't know what turbulence is then. Yes, it absolutely can and they often do. Based on this statement I suspect you don't actually understand turbulence. Many people think about the airline pilot coming on over the...
While the core physics remains unchanged, the presentation is more accessible and engaging, making the content more useful for a broader audience. Mar 11 2025 - New image and video added. Mar 11 2025 - Old title: How Do Mirrors Work? New title: How Does a Mirror Work?
Although the true physics of flying airplanes are quite complex, the whole subject can be simplified a bit - enough for us to get a fundamental understanding of what makes a plane fly, at least!Aerodynamic ForcesEssentially there are 4 aerodynamic forces that act on an airplane in flight, ...
" is an educational and fun game for learning how flying machines work: the plane, the helicopter, the drone and the hot air balloon... Pilot the different aircraft and watch the different forces interact. What makes an airplane fly? How do you turn or descend? How can a hot air ...
The death of his father set a battle raging inside the world's greatest golfer. How he waged that war -- through an obsession with the Navy SEALs -- is the tale of how Tiger lost his way.
4. True or false: The box jellyfish releases venom like a rattlesnake. False. The box jellyfish does not release venom like a rattlesnake. Instead, it releases a "digestive cocktail" that helps the creature catch and digest its meals. Read More: Box Jellyfish: World's Most Venomous Sea ...
