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.

What are the key differences between a bike helmet and a climbing helmet, and how do these differences impact their respective safety and functionality?
A bike helmet is designed to protect against impacts from falls while riding a bike, with a hard outer shell and foam padding inside. A climbing helmet, on the other hand, is designed to protect against falling rocks or debris while climbing, with a more durable shell and better coverage. These differences impact safety and functionality by ensuring each helmet is optimized for the specific risks and activities they are intended for.
What are the differences between a snow helmet and a bike helmet in terms of design and functionality?
A snow helmet is designed to keep your head warm and protect against impacts from snow and ice, while a bike helmet is designed to protect against impacts from falls while biking. Snow helmets often have insulation and ear flaps for warmth, while bike helmets have ventilation for airflow. Both helmets are designed to absorb impact and protect the head, but they are specialized for different activities.
When should you replace a bike helmet after a crash?
You should replace a bike helmet after a crash, even if there are no visible signs of damage, as the impact may have compromised its ability to protect you in the future.
What are the key differences between a ski helmet and a bike helmet in terms of safety and protection?
A ski helmet is designed to protect against impacts from falls on snow or ice, while a bike helmet is designed to protect against impacts from falls on hard surfaces like pavement. Ski helmets often have more insulation and coverage for the ears and back of the head, while bike helmets are more aerodynamic and lightweight. Both helmets are designed to absorb impact and reduce the risk of head injuries, but they are optimized for the specific activities they are intended for.
How does a bike helmet protect your head?
By absorbing some of the impact energy and spreading some of it over a larger surface.
How well does a football helmet protect against impact?
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.
What is the mentally handicapped helmet called?
It's called a helmet. Just like how you wear a helmet on a bike, to protect you when you fall, they wear helmets all the time to protect them when they fall.
Do helmets prevent injury?
Helmets can only protect your head. so if your balls get hit the helmet does not protect them.
Why are people who ride in motorcyles required to wear a helmet?
To protect them against brain injury if they should fall off the bike one way or another.
Why do you use a bicycle helmet?
If you fall and hit your head on the sidewalk, a helmet will keep you from busting your head open. If you fall of a bike and land on your head, a helmet will protect you head.
What is the difference between a ski helmet and a bike helmet in terms of their design and protective features?
A ski helmet is designed to provide protection against impacts from falls on snow or ice, with features like ear flaps and a visor to shield from cold weather. A bike helmet is designed to protect against impacts from falls on hard surfaces, with a sleeker shape and ventilation for airflow during rides. Both helmets have padding and a hard outer shell to absorb and distribute impact forces, but their specific designs cater to the different needs of skiing and biking activities.
What are the safety considerations and regulations regarding the use of a bike helmet for an electric bike?
When using an electric bike, it is important to wear a bike helmet to protect your head in case of accidents. Make sure the helmet meets safety standards and fits properly. Follow local regulations that may require helmet use for electric bike riders.
