By Stephanie Liou 26 Jun, 2011 Glutamate Toxicity. Glutamate is a powerful excitatory neurotransmitter that is released by nerve cells in the brain. It is responsible for sending signals between nerve cells, and under normal conditions it plays an important role in learning and memory.
Fg. Fg is an abbreviation used in physics and engineering for the force exerted by gravity on an object, normally represented in units such as the newton. Fg is always a conservative force. see more on Definitions.net Â».
G-FORCE. When you fly fighter jets you must consider G-forces, or G-load-a numerical ratio of any applied force to the gravitational force at the earth's surface. This is a force that acts on a body as a result of acceleration or gravity and is described in units of acceleration equal to one G. For example, a 10 pound object undergoing a G-force of 5 G experiences 50 pounds of force. The force of gravity on Earth is used as a baseline for measuring these forces of acceleration. As you pull more Gs, your weight increases accordingly.
