G-Force refers to the force of gravity or acceleration on an object, typically measured in units of gravity (g). It describes how much stronger the force acting on an object is compared to the force of Earth's gravity. For example, 1 g is the force we feel from Earth's gravity, while 2 g means the force is twice as strong. In everyday life, we experience G-Force when riding roller coasters or during rapid acceleration in vehicles. Pilots and astronauts also encounter high levels of G-Force during maneuvers, which can affect their bodies and require special training to manage the physical effects.
