G-Force

G-force, or gravitational force, measures acceleration relative to Earth's gravity. It indicates how much an object accelerates compared to the pull of gravity on Earth. For example, 1 G is the normal force we feel standing on the ground. Higher G-forces, like in a fighter jet or roller coaster, cause your body to experience increased pressure, making you feel heavier or pushed against your seat. These forces are important in engineering and safety, as they affect how vehicles are designed and how the human body responds to rapid changes in speed and direction.
