# What&rsquo;s Up with G-forces?

Fighter pilots and racecar drivers deal with serious g-loads every day. But what exactly are they?

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.

WHEN DO YOU FEEL IT?
Most of us encounter g-force during a hard turn in a car or while hurtling along in a roller coaster (in other words, not too often). Fighter pilots, however, experience g-force “with every maneuver you make,” says U.S. Air Force First Lt. James Morgan. “If we are in a dogfight, we’re never going to go straight?we’re going to be constantly turning.”

The nature of gravity or will acceleration, gravitational force is mistakenly called a pulling force and that has screwed up the interpretation of much data, observations, everything for centuries.
It is the very basic assumption of gravity as a force like the other forces is the mistake. Gravitational force is, without depth of explanation here, ian emitted wave alignment, a field synchronization force. Simply stated, all gravitational forces are synchronizing fields emitted from all matter, energy. Wave tension creates gravitational force, increase wave
tension, increase gravitational force. The gravitational constant is the path of least resistance constant as mass to mass
aligns generating fields. It is the missing backaction of the Huygen's Principle. Gravitation@cfl.rr.com
