Well helmets have cushining inside them so that serves as a shock absorber. The lightweight and soft medium between your head and the object colliding with it dims the force.
For example, yelling through an empty hall will allow the sound to travel easily, but if you stuck in another wall reaching from roof to floor with no gaps then the sound would be dimmed out and would have a smaller impact. The wall would absorb the sound.

Like the old saying goes, It isn't the fall from the roof of the building that kills you, it is the sudden stop at the end...
The same is true of ANY collision. The trick is to DECELLERATE the cranium ( your head ) slowly ( or not as fast ) during the actual impact. Modern helmets not only protect from penetration, they also are designed to CRUSH in order to have the crainium decellerate slowly. That is why you NEVER reuse a helmet afer a collision or when it is damaged. It cannot protect you.
Cars are desgned with crush areas nowadays. They help you survive a collision.

the helmet contracts when force is applied to it. that force is then taken by the helmet and not the skull. once it is fully contracted and has absorbed all it can the remaining force hits the skull. the helmet also helps to spread the force evenly around the skull so it doesnt all hit at the same spot.

the selection one reason of early existence incapacity is head injury. almost all of which could be prevented with somewhat uncomplicated experience. We did no longer have motorbike helmets while i replaced into youthful yet they are right here immediately. it incredibly is not any longer in basic terms falling over or off that reasons babies to get injury on motorcycles. autos do besides, a helmet will help to lesson the wear even in a vehicle twist of fate.

helmet 2 layers
Hard outer to stop penetrating injuries.
Foam to compress to reduce shock to the brain. Energy transferred to action of compressing foam. Also force is evenly distributed.

Because the helmet cracks instead of the rider's skull cracking?

It's like socialism. It doesn't reduce the force, it just redistributes it more evenly.
