You are confusing the ability to sustain the g-force by the brain with the force experienced. A padding on the helmet helps in event of collision, not the g-force which is due to the acceleration
- pengaru 6y agoHow is a collision not just another acceleration?
- amluto 6y agoIn a collision, the helmet gets hit and, subject to some degree of padding and such, transfers the impact to the head. If you’re sitting in a sled and the sled accelerated rapidly, your head and your helmet must accelerate with it, although you may not perfectly track its path. Unless the helmet is also secured to your torso, all the forces on the helmet come from your head. You would need tremendous acceleration of your head to meaningfully deform any but the softest padding.
- refurb 6y agoSure the helmet helps with g-forces. Say you're going down the track and enter a tight turn. The helmet contacts the side of the sled at say 5 g's because the helmet is hard and so is the side of the sled. The brain impacts the helmet, which impacts the side of the sled, but the padding in the helmet spreads that impact over a greater period of time, since the padding compresses, so the brain only experiences a g-force of 2.
