In this experiment I predict as the number of blades increase the time it takes for the mass to fall will be slower because as the number of blades increase the air resistance will increase thus making the mass drop slower.

Air Brake assessment Planning Prediction In this experiment I predict as the number of blades increase the time it takes for the mass to fall will be slower because as the number of blades increase the air resistance will increase thus making the mass drop slower. But I also predict after a certain number of blades the mass will start to drop faster because the blades will be so close together that it will be hard to gain a lot of air resistance because there is not a large surface area for the air to enter. Which means air resistance will not be as much between the blades thus meaning there is not as much air to be used in the air brake compared to the beginning of the experiment and this will make the mass drop faster. In this prediction we decided to do 10 values for the blade...
