What term is used for the force applied from the front of the body to the back?

The correct term for the force applied from the front of the body to the back is longitudinal G force. This force is experienced while the aircraft accelerates or decelerates, creating a sensation that pushes the body forward or backward depending on the direction of motion. In aviation and aerospace contexts, understanding longitudinal G forces is crucial since they impact the physiological effects on the pilot and can influence their ability to control the aircraft effectively.

In contrast to longitudinal G force, transverse G force refers to side-to-side movement, lateral G force typically involves forces acting perpendicular to the direction of travel (such as during turns), and vertical G force pertains to the forces acting up or down on the body. Each of these terms describes a distinct directional force, and recognizing these differences is key to understanding the specific effects experienced by individuals in various flight maneuvers.
