Tốc Độ Siêu Thanh

Mach is a velocity measure defined as the ratio of an object"s velocity khổng lồ the tốc độ of sound. In other words, the Mach speed corresponds to lớn the number of times an object has reached the tốc độ of sound. The speed of sound is not constant và depends on the medium where the sound is propagated. In the Earth"s atmosphere, if we take into tài khoản a temperature of approximately 15 degrees Celsius, the tốc độ of sound is 1225 km/h. This is the reference measure used by the Mach speed, và thus, Mach 1 corresponds to lớn exactly that value. The air force has combat aircraft with speeds several times higher than the tốc độ of sound, they are the so-called supersonic planes. Most of them can fly at a tốc độ equal lớn or greater than Mach 4, that is, four times the tốc độ of sound.

There are already some projects for the construction of airplanes that can reach the surprising speed of Mach 20.

Kilometer per hour is a measure of speed, typically used in countries that use the metric system. In these countries, road speed limits are calculated in kilometers per hour, which is abbreviated as kph or km/h. As its name implies, this unit represents the distance (in kilometers) traveled by an object for one hour. This measure is usually an average, that is, if a oto traveled the distance of 210 km between two cities and to take this route, it took an hour and a half, so we will get a tốc độ of 140 kilometers per hour (140 km/h). This does not obviously mean that the oto has constantly shifted at this speed, there may be parts of the route on which it has been faster and parts where it has circulated more slowly.
