How fast do you have to go to experience 2G's, 3G's, 4G's and 5G's?

Question

Ok, since its got to do with acceleration,

0-100km/h in how many seconds gives you

2Gs

3Gs

4Gs

5Gs

Answer 1

It depends on acceleration and not on velocity.  

Answer 2

Assuming you're accelerating straight up, the 1G from the Earth's gravity will add to the Gs from your acceleration.  You would need to go from 0-100km/h in the following times:

2Gs = 2.83 seconds

3Gs = 1.42 seconds

4Gs = 0.94 seconds

5Gs = 0.71 seconds

If you don't want to count the Earth's gravity, and just want the Gs from your acceleration, subtract 1G from those numbers (1G = 2.83 seconds).

Answer 3

It's nothing to do with how fast you are going; but how fast your velocity (a vector) is changing.

Answer 4

i think experiencing G's depend on your downward deceleration. going really fast will only allow you to experience mach speeds.

correct me if i'm wrong, i haven't been studying physics since last year
