An investigation on padding pressure in football helmets
The experimental data and analyzed results do not support the hypothesis that a higher padding pressure in football helmets lowers the force of impact experienced by players during head-on collisions. Instead, the experimental results showed a positive relationship between the pressure in the padding and the pressure in the air bag. This means that a helmet with more pressure in the padding will lead to players suffering a more severe head injury in a collision.
The helmet is the most important protective gear in American football. In the past, players used skull caps made from leather to protect their heads, whereas players nowadays use plastic helmets that are molded using very hard plastic material. Helmets are important as they protect the players from serious head injuries.
Try to repeat the science fair project using a wider range of air pressures for the helmet padding.
The science fair project can also be repeated using heavier weights to simulate different collisions.

Caution should be taken to prevent the falling weight from hitting anyone
