G-Force effects refer to the forces of acceleration that act on a body as it moves through space. These forces are measured in units called "g's," where 1 g is equivalent to the force of Earth's gravity. When an object accelerates quickly, such as during a roller coaster ride or in a fighter jet, the body experiences increased weight, which can lead to sensations of pressure or even loss of consciousness if the forces are too strong. In everyday life, we experience G-Force effects during activities like driving or riding in an elevator. For example, when a car accelerates rapidly, passengers feel pushed back into their seats due to the increase in G-Force. Understanding these effects is crucial in fields like aviation and space travel, where pilots and astronauts must be trained to handle high G-Force situations safely.
