G-force is a measure of acceleration, not of speed; one G is the equivalent acceleration to one normal Earth gravity. 9 Gs is equal to nine times the force of gravity, and the object weighs nine times as much - it is enough to make all but the most experienced and well trained fighter pilots to blackout.
The maximum acceleration in gs that a human body can withstand before experiencing physical discomfort is typically around 5 gs.
Depends on the person, most would black out when going at 3 or 4 G.============================================Answer #2:"3G" and "4G" are not speeds, and speed doesn't cause anyone to black out.Speed imposes no stress on the body at all.Stress is imposed by CHANGE in speed. Speeding up, slowing down, or rounding a curve too drastically. Those changes are called "acceleration", and can be measured in 'G's.The correct question is: How many Gs of acceleration will cause you to black out ?
454g in a pound
If a car travels twice as fast, it will skid four times farther because kinetic energy increases with the square of speed. If the car travels three times as fast, it will skid nine times farther compared to its initial speed.
5 nanoseconds is extremely fast – it is one billionth of a second. To put it into perspective, light can travel approximately 15 cm in 5 nanoseconds. It is a common unit of measure used in computer processing speeds and electronics.
