Description | ||
| 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. | ||

| 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. 2. Arrange the four bricks in ..... | ||
