Which term is used for objects traveling at Mach 5 or faster?
Turbosonic
Supersonic
Hypersonic
Ultrasonic
Correct Answer: Hypersonic
Fact: Objects traveling at Mach 5 or faster are referred to as hypersonic. The term “hypersonic” applies to speeds that are five times the speed of sound or greater, typically exceeding 3,800 miles per hour. Hypersonic travel is a key focus in advanced aerospace and military technology, particularly in the development of hypersonic missiles, aircraft, and space reentry vehicles. These objects experience extreme aerodynamic heating and require specialized materials to withstand the intense thermal and pressure conditions encountered at such high velocities.
