G-force, or gravitational force, refers to the measurement of acceleration felt by an object or person in relation to the acceleration due to gravity. It is often expressed in units of "g," where 1 g is equivalent to the acceleration of gravity at Earth's surface, approximately 9.81 meters per second squared (m/s²). When experiencing G-force, people or objects feel heavier or lighter depending on the direction and magnitude of the acceleration.
