Question: how many g's do astronauts experience during takeoff
Answer: A three - axis accelerometer will output zero ‐ g on all three axes if it is dropped or otherwise put into a ballistic trajectory ( also known as an inertial trajectory ) , so that it experiences `` free fall , '' as do astronauts in orbit ( astronauts experience small tidal accelerations called microgravity , which are neglected for the sake of discussion here ) .
