It gives the head a pad of protection, not all the protection in the world though, that's why today you see all these players getting concussions
A helmet prevents the head from taking a direct impact with some solid object.
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.

es, that is the topic of my science fair project......
Yes, but it is not recommended. Helmet manufacturers recommend helmet replacement after any impact to the shell. A motorcycle helmet is designed to absorb the impact and damage that would otherwise be reserved for your skull, but it is not designed to survive the impact. Any impact from a drop on solid ground (concrete or hardwood floor) can cause microfractures to the shell that are naked to the human eye. A good rule of thumb is this: If the impact would have raised a bump on your unprotected head, get a new helmet.
By absorbing some of the impact energy and spreading some of it over a larger surface.
if in good condition it is designed to destroy its self before u get hurt
Helmets can only protect your head. so if your balls get hit the helmet does not protect them.
Really it depends on the velocity and how hard you hit someone. or how big or tall.
they are both intende to protect your brain from impact's and are both hard except for babies because they usually have a soft spot on the top of their head for a length of time after they are born.
To protect your knees against both impact and abrasions if you should take a fall.
