* It’s called gravity accelaration in physics.
Objects which near the earth’s surface, while their accelerations are only effected by gravity, called gravity acceleration, also called free fall acceleration, with g said.
Gravity acceleration (g) is always vertical downward direction. In the same place, the gravity acceleration of any object is the same. Theoretical analysis and precise experiment show that along with the increase of latitude, the numerical value of gravity acceleration (g) increased slightly, such as near the equator g = 9.780 m/s , the arctic g = 9.832 m/s . Because g value change little along with latitude, so international admiral in 45 ° latitude of sea level gravity acceleration g = 9.80665 m/s as gravity acceleration standard values. In solving problems near the earth’s surface, it is often g as a constant, in general calculation can take g = 9.80 m/s .
The numerical gravity acceleration decreases by altitude rise. When object apart from the ground height far less than earth’s radius, g will change a little, but from the ground height great, the gravity acceleration g numerical significantly reduce, under this condition g can’t be considered as constant.
* G-value in F1 formula racing
G is gravity acceleration unit, the values of about 10 meters per second. Our human beings or objects in normal circumstances with a stationary state effected by gravity acceleration is 1 G.
F1 is basically a kind of planar movement, so when we watch the live show on TV program we can see that around the G cost of the four directions. When car accelerate, the driver should get back, turn left when the driver turn to the right direction etc. If go to ride the roller coaster, we’ll be able to feel the acceleration from the up and down around six direction, but G value were never more than general 3, because the average man when feel more than 3 G value will feel particularly afflictive.
It is said that astronauts in the launch of the acceleration down feel more than 6 G (they should burden more 6 times of their self-weight) while training should reach to 10 G, obviously, not everyone can do it. In addition, 0 G is very comfortable (in the bungee jumping), a little bit safer method for feeling it, it’s that play the pirate ship and sit in the last row, when swing to the peak, there will have a brief comfortable feeling.
* What is G-value in car accleration?
Acceleration G value:
How much time a car need when accelerate to the speed of 100km/h. The least time need, the greater value show.
Deceleration G value:
How much time a car need when decelerate to the speed of 100km/h. The least time need, the greater value show.
