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
* Force = Mass X Acceleration.
* We want to reduce the force your head experiences so according to physics, we can only reduce two things, the mass involved, and/or the acceleration.
* Well we can’t really reduce the mass of your head, or anything that might hit it.
* So the only left is to reduce the acceleration.
* But what is acceleration?
* It’s how quickly you change speed.
* When something hits your head, the damage is usually done because your head was moving and *very very* *quickly* it comes to a stop.
* So we need to increase the amount of time it takes to make your head stop.
* This is where the helmet comes in.
* It’s designed to cushion your head.
* Instead of hitting something hard that won’t move, it hits something soft that moves a little.
* This slows down your head just enough to decrease the force applied enough to prevent major injury.
