The speed of sound is proportionally less and vary s according to altitude. when ever air craft exceeds the speed of sound it is defined as i mach. those air crafts capable of crossing sound speed is called supersonic.
The threshold for supersonic speed is 761 mph in a temperature like 70 degrees. Supersonic speed is any speed greater than the speed of sound (mach 1) and a speed five times the speed of sound (mach 5?) is referred to as hypersonic speed.
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.
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.
One half the speed of sound. This is subsonic.
The word for 5 times the speed of sound is "supersonic."
One supersonic aircraft is the F-15 Eagle. -Supersonic means it can fly faster than Mach 1, the speed of sound. Most fighter jets today are supersonic, in fact many fly more than twice the speed of sound.
Yes, a supersonic jet travels faster than the speed of sound, which is approximately 767 miles per hour at sea level. Supersonic jets can reach speeds up to Mach 2 or more, which is twice the speed of sound.
A supersonic plane travels faster than the speed of sound, which is approximately 343 meters per second (1,125 feet per second) at sea level and standard atmospheric conditions. Supersonic speeds typically range from Mach 1 (the speed of sound) to Mach 5, with many military jets and experimental aircraft exceeding these speeds. For example, the Concorde, a commercial supersonic airliner, cruised at around Mach 2.04, or about 1,354 miles per hour (2,180 kilometers per hour).
They are called Supersonic aircraft. Some aircraft can only do that. Some planes have reached even Hypersonic speeds.
a mach
The Concorde was a commercial supersonic jet that traveled faster than the speed of sound. It had a top speed of around Mach 2, which is about 1,354 miles per hour.
Mach refers to the speed of sound in air. Typically about 750 mi/hr but it varies faster or slower with temperature from cold to hot respectively. Mach one is one times speed of sound. Mach 3 would be three times speed of sound.
