In aerodynamics, what term is commonly used to describe acceleration in relation to gravity?

The term "G Force" is used to describe acceleration in relation to gravity because it measures the force experienced by an object due to acceleration, which can be influenced by gravitational pull. Specifically, "G Force" refers to the acceleration relative to the acceleration due to Earth's gravity, which is approximately 9.81 m/s². When objects accelerate, such as during high-speed maneuvers in an aircraft, pilots may experience increased forces that can be expressed in terms of Gs. For instance, experiencing 3 Gs means the pilot feels three times the force of gravity acting on them.

In this context, the other terms do not relate directly to the measurement of acceleration in the same way. The drag coefficient pertains to the aerodynamic resistance an object faces as it moves through a fluid like air; thrust refers to the forward force produced by engines; and lift is the upward force that allows an aircraft to rise and stay in the air. None of these concepts directly describe acceleration in relation to gravity like G Force does.
