Just how fast is Sonic? Tap to find out if Sonic the Hedgehog can outrun a 747. Sonic Runners Adventure The Action Platformer Legend View We all know Sonic the Hedgehog is really, really fast. Since his debut on the SEGA Genesis in 1991, the blue blur has zoomed through giant pi...
This lack of friction and the trains' aerodynamic designs allow these trains to reach unprecedented ground transportation speeds of more than 310 mph (500 kph), or twice as fast as Amtrak's fastest commuter train [source: Boslaugh]. In comparison, a Boeing-777 commercial airplane used for ...
Staying in the Air The string on the windshield tells the pilot if the plane is yawing The wings on a glider have to produce enough lift to balance the weight of the glider. The faster the glider goes the more lift the wings make. If the glider flies fast enough the wings will pro...
The progression of Parker Solar Probe is shown hrough the fields of view of the STEREO/SECCHI telescopes. The images are simulated, based on data from earlier in the STEREO mission.Stereo Science Center/NASA How fast is the Parker Solar Probe traveling? The Parker Solar Probe is traveling at...
How fast is light speed?Speed:Consider a kid running in the garden for a certain time duration and covers some distance during this time period. In this case, the speed of the kid can be given as the distance divided by the time duration and it is measured in meter per second....
It's all very impressive, but it can be hard to wrap your head around in the abstract, so let's do a little bit of napkin math to really bring it home. First, let's establish some terms. Hypersonic is, obviously, supersonic on steroids. But while "supersonic" has the clear cut ...
The Shinkansen network has expanded steadily since the 320-mile Tokaido line, linking Tokyo and Shin-Osaka was completed in 1964. Trains run at up to 200 mph (about 322 kph) on routes radiating out from the capital – heading north, south and west to cities such as Kobe, Kyoto, Hiroshima...
April's total solar eclipse will travel at speeds ranging from 10 million miles an hour — half the speed of the fastest supernova explosion ever detected— to as slow as 1,565 mph, about twice the speed of a supersonic aircraft. Just ensure you're inside the path of totality to stand...
Combustion occurs in the engine only at supersonic speeds because the air has to be flowing at a high rate to be compressed. Rather than using a rotating compressor, like a turbojet engine does, the forward velocity and aerodynamics compress the air into the engine. Hydrogen fuel is then in...
In a supersonic combustion ramjet, or scramjet, an air inlet draws in air. The air is slowed and compressed as the vehicle speeds through the atmosphere. Fuel is added to the supersonic airflow, where the two mix and burn. Fuels most likely to be used with the air-breathing rockets ...
