Overview

G-force is a measurement of the type of acceleration that causes a perception of weight. It is expressed in units of standard gravity (g).

💡

Pro Tips

1G is equal to the gravity we feel standing on Earth.
High G-forces can cause blackouts (G-LOC) in pilots and astronauts.
G-force is a vector quantity, though often measured as a scalar magnitude.

Fun Facts

"Roller coasters typically reach between 3G and 5G."
"F1 drivers experience up to 5G while cornering."
"The highest G-force survived by a human in a recorded test was 46.2G (John Stapp)."

Formula: G = a / 9.80665
