The objective of this science fair project is to determine whether different padding pressures in football helmets on reduces the impact experienced by football players during head-on collisions. A 5 kg circular weight will be used to create the collision, and its effect on helmet padding pressures of 750 mmHg, 800 mmHg, 850 mmHg and 900 mmHg will be observed.
A higher padding pressure in football helmets will lower the force of impact experienced by players during head-on collisions.
Force, impact, pressure
Materials required for this science fair project:
1. The independent variable in this experiment is the air pressure applied to the padding in the helmet. The dependent variable is the increase in the pressure inside the air bag on collision with the 5 kg weight, which is determined by measuring the maximum deflection in the air pressure gauge. The constants (control variables) are the height at which the weight is dropped , the mass and size of the weight, the size and brand of the helmet, the size of the air bag, and the initial pressure in the air bag.
Increasing the pressure of the padding in the football helmet led to an increase in pressure inside the airbag during collision with the weight.
Use the graph below to plot the experimental data recorded in the table above.
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.
