So your head didn’t hit the stone of the road, I guess that helps.
But, you still hit your head on *something,* essentially. The inside of your helmet.
All that force is still in there, right?
In: Physics
Helmets help by spreading the impact out over a larger area, and by spreading the impact over a larger period of time. Cushioning stretches the impact over time so the force at any given moment is lessened. Think jumping onto a big cushion as opposed to the ground; you stop either way but slower hurts less. A firm outer covering spreads the impact over an area so the force on any given area is reduced. Think being pushed as opposed to being stabbed; stabbed hurts more because focused force will be enough to damage tissue.
