By spreading and absorbing the force of impact.
Your head is kinda rounded, meaning that if you hit even a flat surface, the contact area between head and surface is fairly small.
Meaning all the force of the impact has to go through a small area and quickly gets quite high.
With a helmet, whose inside is more like the shape of your skull, the force of impact is spread over a larger area, meaning the spread-out force becomes lower.
Less force, less damage.
Also, while a helmet feels firm to the touch, if you bang it hard, it'll compress.
And compressing the helmet material soaks up energy that otherwise would have gone into your skull. Less energy, less damage.
The last thing a helmet will do is to break apart. And just like it takes energy to break a stick, breaking a helmet ALSO takes energy.
And the energy that gets used up breaking a helmet, is ALSO energy that's been prevented from going into your head, doing damage there.
Well, a bike helmet is sometimes made out of steel or plastic, so I say just to be sure look on the internet and look it up before you do anything major!
By absorbing some of the impact energy and spreading some of it over a larger surface.
Can't tell if you've accidentally placed this question in the wrong category, or if you want to use a motorcycle helmet for bike riding. But basically any helmet is better than no helmet, but a helmet built for the intended usage is better than just using any helmet. In this case a football helmet is designed to be able to take several hits with lesser energy than compared to a motorcycle helmet. An MC helmet is expected to protect against one massive hit and then to be discarded.
