G-FORCE—WHAT IS IT?
You’ve seen us mention g-forces in articles about new jet aircraft and cars?many times with reference to their being a very serious obstacle to overcome when developing ever faster technology. But what are they? Gravitational force is the force of gravity pulling you toward the Earth. When you undergo a change in speed and direction, that force increases in proportion to the rate of change. To calculate the magnitude of the force you feel as g’s increase, multiply your weight by the number of g’s.
