Now “acceleration” means change in velocity, which means any change in speed or direction.
At 1g, the speed changes by 10 m/s (22 mph) second, hence 10 m/second-squared.
High g-forces are a big problem for astronauts, fighter pilots and racing drivers.
It is used because the weight force is proportional to mass, while acceleration is inversely proportional, so the acceleration of all objects due to gravity is equal.
This explains Galileo’s apocryphal experiment of dropping a heavy ball and a light ball from the Leaning Tower of Pisa, and finding that they hit the ground at the same time (except for air resistance).
At the earth’s surface, the acceleration due to gravity is 9.80665 m/s², or 1 g, which will be rounded to 10 m/s² for the “back of the envelope” calculations in this article.
