Breaking the sound barrier refers to exceeding the speed of sound, which is approximately 343 meters per second (or 1,125 feet per second) in dry air at sea level and 20 degrees Celsius. The concept of "G's" refers to the acceleration due to gravity, which is approximately 9.8 meters per second squared on Earth.
It's important to note that the acceleration due to gravity does not directly relate to breaking the sound barrier. Breaking the sound barrier is primarily dependent on the speed of the object relative to the speed of sound.
To break the sound barrier, an object needs to reach a speed faster than the speed of sound, which is approximately 1,225 kilometers per hour (or 761 miles per hour) at sea level. This speed is often referred to as Mach 1.
The acceleration experienced by an object depends on its design and the forces acting on it, such as thrust, lift, and drag. It is not directly tied to the concept of G's. However, during the process of breaking the sound barrier, the forces and accelerations experienced by the object can be significant.
In summary, breaking the sound barrier is determined by achieving a speed faster than the speed of sound, and it is not directly related to a specific number of G's.
