Is it something to do with the weight of an astronaunt?

it is the force of gravity it's simply 9.8 m/s/s or 32ft/s/s
acceleration of gravity is -9.8m/s/s or 32ft/s/s
g force is just the absolute value

G force is commonly known as "gravitational force", that is the force of gravity that is exerted on every object on Earth. When it is associated with rocketry, scientists need to calculate the effect that the g-force will have on the rocket. A rocket must be able to overcome the g-force in order to fly upwards. Upon entry back to Earth, the rocket will accelerate due to the g-force acting on it.
Gravitational force is an acceleration. It is roughly 9.81 m/(s^2).
When you hear 2g's or 3 x the g force, it just means twice or three times the force of gravity.
In terms of the weight of an astronaut, a person's weight is measured in Newtons (N) and is dependant on the gravity or g-force. If there is no gravity, there is no weight. If there is more gravity than Earth (say if an astronaut were on a larger planet), the weight of the astronaut would be more. Please don't confuse weight with mass.

To launch a rocket with the smallest quantity of gas, you want to accelerate it as a lot as attainable, regrettably that's problematical on the crew. 4g is like being 4 circumstances your common weight. imagine accelerating very gently far flung from Earth; in an severe case you would purely hover, use a huge quantity of gas and get nowhere. once you re-enter, you remember totally on air friction to sluggish you down. in case you re-enter at too steep an attitude, you'd be subjected to as a lot as 200g, which may kill you. you purely get one shot; in the adventure that your attitude is purely too shallow, you shoot off into area again, and also you've already used all of your gas to drop out of orbit. Your re-get perfect of entry to course must be impressive to interior about one degree. If the Earth's gravity became only a touch better, then area commute will be no longer attainable with immediately's chemical rockets. we would might want to look ahead to nuclear-powered rockets, which have were given some glaring negative aspects even as used contained in the ambience.

It refers to the force of gravity. One g is equal to one times the force of gravity, which is normal. Two g's is two times the force of gravity. There is also negative g force, which is just the opposite.

"G force" refers to gravitational force. Per Einstein's Theories of Relativity, gravity and acceleration are the same thing (he proved it mathematically), which is why we experience g-forces in motion. It's also why you feel a pull when taking off or stopping in a car.

The G stands for gravity. When you ride in machines they push you in different directions, the faster you go the more gravity you feel. 5 gees is five times your body weight, to many gees will knock you out.

g refers to gravity...2 g = 2X gravity, where 5 lbs will feel like 10.
and so on.

The pull of Gravity, for Pete's sake.
