The force of gravity on Earth is used as a baseline for measuring these forces of acceleration. For example, a 10 pound object undergoing a G-force of 5 G experiences 50 pounds of force.
This is a force that acts on a body as a result of acceleration or gravity and is described in units of acceleration equal to one G. When you fly fighter jets you must consider G-forces, or G-load - a numerical ratio of any applied force to the gravitational force at the earth's surface. To read more about Mach and speed of sound please visit You can calculate your speed at different altitudes using Mach number and compare it to the speed of sound at NASA website,
When an aircraft exceeds the so-called sound barrier a large pressure difference is created in front of the jet thus causing the sonic boom. Jet flights are normally classified in the following categories: The higher Mach number you see on the control device the higher is the speed of the aircraft. Mach number (named after Ernst Mach, Austrian physicist) is the speed of an object divided by the speed of sound (with air temperature 20° C 343 m/s or 1235 km/h or 770 mph). We would like to give you some basic explanations before your flight so it will be easier for you to understand:Īir Forces generally use the term “Mach” to define the speed of the aircraft. When preparing for MiG adventure your pilot will describe your flight envelope using various terms from physics, and some of them you will even see on the control devices in the cockpit. Speed and G-force - supersonic flights on military fighters MiG in Russia
