1) The mass of the wooden bokken is directly proportional to the amount of force it inflicts.
2) Dependent: Amount of force done by the sword.
Independent: Type of wood that will be used.
Control: Height the sword will be dropped at.
3) This experiment pertains to my EQ because to be a successful aikido practitioner you need training. When you train with weapons you want to make sure that you get a strong, well made bokken or jo. I am going to be finding which bokken is the strongest; thus showing which bokken is best for training.
4) I will buy a number of bokkens, each made from a different kind of wood. Then I will be testing the strength of the wood with a vernier force plate (it measures, in Newtons, how much force was applied on the plate). The sword will be attached to a pole, probably with some sort of string; I will bring the sword up to a certain height, and let the sword drop. When the sword falls the tip will swing in an arch shape and hit the force plate; I will record the amount of Newtons, and move on to the next wood.
5) Mathematics and Computer Science.
