By definition, Mach 1 is the speed of sound. Most of the time it is used to refer to the speed of sound in air, but it can be used to refer to the speed of sound in any fluid. Mach numbers are multiples of this speed, so Mach 0.5 is half the speed of sound while Mach 2.5 is two and half times the speed of sound. The term "transonic" refers to a condition where the speed crosses over the speed of sound - so it refers to a range of velocities of airflow exist surrounding and flowing past an air vehicle or an airfoil that are concurrently below, at, and above the speed of sound in the range of Mach 0.8 to 1.2. In this respect - at least some of the velocities must be below the speed of sound, some at the speed of sound and some faster. The correct term for speeds that are exclusively faster than Mach 1 is supersonic.
Very much so.
The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
Close! Actually, Mach-1 is the speed of sound. anything above Mach-1 (Mach-(1-5)) is supersonic, all the way up to Mach-5, at which point an object is called "Hypersonic". Sometimes speeds above Mach-10 are referred to as "High-Hypersonic". So, a jet moving at Mach-1 wouldn't actually be traveling FASTER than sound, it would be traveling AS FAST as sound.
Supersonic No. The fastest ever flown was mach 3.1 by the SR-71 Blackbird
The type of aircraft that flies faster than the speed of the sound are called SuperSonic aircraft.There are many supersonic aircrafts. Nowadays there are also HyperSonicaircrafts. The maximum speed recorded is Mach 9.6 (9.6 times faster than the speed of sound) by X-43A.
1 mach equals 340 m/sec that is, 1224 Km per hour. Speeds over that limit are ultrasonic.
Actually, transonic speed is not a speed faster than that of sound. Transonic speed is approx. Equal to the speed of sound, not faster.
Faster than the speed of sound.
No, Mach 20 is not faster than the speed of light. The speed of light is approximately 299,792,458 meters per second in a vacuum, while Mach 20 is roughly 7.35 kilometers per second. Therefore, Mach 20 is significantly slower than the speed of light.
Mach 5, 5 times faster than the speed of sound!
Mach 5, 5 times faster than the speed of sound!
A supersonic plane is one that is flying faster than the speed of sound, or Mach 1. A hypersonic plane flies at a speed of Mach 5, so is much faster than a supersonic plane. Mach numbers are used for speeds greater than the speed of sound.
Very much so.
Bullets flies at the top speed of Mach 3 but almost Mach 4. There are some planes that can fly much faster than bullets but bullets used to fly faster than most planes(aircraft). Hypersonic aircraft can fly up to Mach 9. So yes, hypersonic aircraft can fly much faster than bullets. If these hypersonic planes can fly faster than bullets, they can fly alot faster than missiles. Missiles also flies around Mach 3 but hypersonic planes don't fly at that kind of speed. The top speed that hypersonic planes is nearly Mach 10(almost 10 times faster than the speed of sound).
The speed of sound does not travel. In the event that an airplane's airspeed is below Mach-1, the speed of sound is faster than the speed of the airplane. On the occasion and at the moment when the true indicated airspeed of an airship or an airplane is in excess of Mach-1, the airplane is at that time traveling faster than the speed of sound.
x 15 is faster then the sr71 blackbird who can only reach a speed of mach 3.2 which is 3 times the speed of sound but the x 15 can reach mach 6.72
