The swooping, sickening sensations you experience on a roller coaster come courtesy of brief g-forces of up to. Rides have to be designed so people dont black out. Our tolerance of g-forces depends not only on the magnitude and duration of the acceleration or deceleration but also on the orientation of our body.
Heres what ive recently learned about gravitational force what exactly is gravitational force. Rookies couldn't hope to withstand more than about 5 or 6 g read more.
The limiting factor is likely to be forces on the air we have in our lungs, nose, ears etc. Or, more aptly, the lack of oxygen to feed the brain that only blood flow could provide.
So, how many g-forces how many times the earths gravitational acceleration could a person in a water tank withstand. The blood would no longer tend accumulate in the direction opposite to that of the acceleration. To figure out what portion of the gs gets adds weight to the tires, you multiply the g-forces by the sine of the banking degree.
But ive never really understood how g-forces work and how many gs do what to your body until now. Could you envisage shooting someone into space using a cannon, as jules verne proposed for going to the moon. I bet youre asking, what is g-force, anyway.
