In thrill machine rides at amusement parks, there can be an acceleration of 3gram or more. But without head rests, acceleration like this would not be save. Think Why not?
Question asked by: ali shah

If there is too much acceleration and there are no headrests then you could experience whiplash or worse, where the head is thrown backwards and there is tremendous pressure on the neck to stop the head being thrown back - this is dangerous and can cause people to feel ill, woozy pass out and even worse.
