What is G FORCE?

Question

I still do not understand the meaning of G Force, and why it can cause so much harm to the human body, is spinning around in circles creating G Force? Im Confused, Please HElP

Thank You!

Answer 1

It is the force exerted per kg of mass 9.81N on Earth

So 1 G = 9.81N per Kg

Excess G Force can put too much stress on the body so that it is damaged and eventually can crush. It can also drain blood from the brain (blackout) or the opposite in negative G (Red out)

When you spin in circles, you create a centrifugal force pulling everything to the centre of the circle. They can use this technique in space to simulate gravity

Answer 2

G Force Test

Answer 3

G force is the energy that causes dollar bills to get stuffed into G-strings.

I just had to say that. When you accelerate, the force of gravity increases (F=MA). Spinning is caused by centrifugal force, which is related to G Force. An object traveling in a circle is constantly changing directions, and therefore in a state of perpetual acceleration in a new direction.

Spinning is used to simulate effects of G Force on pilots. G Force has biological effects when it exceeds the force of blood pressure or the bursting strength of blood vessels. If the G force is greater than a person's blood pressure, the blood travels in the direction of the gravitational pull instead of circulating in a normal pattern. So upward acceleration causes blood to pool in the legs, and downward acceleration causes blood to pool in the head. 2-3 G can cause a person to pass out in a few seconds and can also cause hemorrhaging in the capillaries. Arteries and veins can only withstand G Forces of 5-7 G before they rupture.

Answer 4

G stands for gravity. Jet fighter pilots have to endure high g forces when they execute tight turns or manuovers. The high centrifugal forces are equivalent to multiplying the force of gravity. G forces are also encountered during rapid acceleration or deceleration, as when a vehicle comes to an abrupt stop. When the space shuttle accelerates into space, the astronauts are subjected to high g forces, and again when the space shuttle re-enters the atmosphere and decelerates. To train for the high g forces, astronauts are put into a centrifuge, which spins around in circles. At around nine or ten gees, a person can loose consciousness, because his effective body weight is ten times normal.

Answer 5

G Force refers to gravitational force. The reason it can cause so much harm to the body is that it causes compression and pressurization of organs and tissues. Spinning around in circles causes centrifugal force, which has the same effect.

Answer 6

G force is 1. gravity exerted by the Earth or other bodies on you and 2. a sort of slang for centrifugal forces generated by spinning or turning an object. If you're in a car taking a sharp turn you're experiencing centrifugal force, but sometimes people call it 'g-force'.

Answer 7

G force is the amount of force exacted on the human body. G stands for gravity--therefore 10 Gs is a force exerted 10 times that of gravity. A alot of G force can be unpleasant and harmful because it's a lot of unnatural pressure placed on the body.

Answer 8

If you have ever sat in a car rapidly accelerating the effect you felt being thrown againt the seat is "G Force" =32 Ft/sec/sec.

Riding in an airliner the average passenger endures a couple of "G's" on take off.

Sustained g forces put stress on internal organs, deflect blood circulation, which can cause black-outs when continued at higher levels.----not on airlines ususally.

Pilots/astronauts are tested in centrifuge which simulates elevated g forces by means of centrifugal force. This is to test them for their endurance and to acquaint them with it to recognize its effects to deal with them in flight.

Answer 9

Gravitational Force: The effect of the earth's gravity, mimicked and magnified through speed, causing pressure and external forces on a body or what ever's being subjected to it.
