Orbital Mechanics How Things Works
Orbital Mechanics How Things Works YouTube Video : Deep Science | Documentary Tapes Gravity & Mechanics PAGE 4 OF 4 ON THIS PAGE How Orbits Work The Key to Space Flight Orbiting a Real Planet A Periapsis by Any Other Name Freefall How Orbits Work These drawings simplify the physics of orbital mechanics, making it easy to grasp some of the basic concepts. We see Earth with a ridiculously tall mountain rising from it. The mountain, as Isaac Newton first described, has a cannon at its summit. Of course, in order to make their point, the cartoons on this page ignore lots of facts, such as the impossibility of there being such a high mountain on Earth, the drag exerted by the Earth's atmosphere on the cannonball, and the energy a cannon can impart to a projectile ... not to mention how hard it would be for climbers to carry everything up such a high mountain! Nevertheless, the orbital mechanics they illustrate (in the absence of details like atmosphere) are valid. N...
