The purpose of this study is to use rotational kinetic and gravitational potential energy calculations in quantifying the energy absorbed by surrogate Popsicle sticks and chicken bones upon fracture by an impact pendulum apparatus.  In addition, this experiment aims to determine the influence of the pendulum apparatus’ speed immediately before impact on the energy absorbed by the surrogate Popsicle sticks and chicken bones.  In pursuit of this objective, the pendulum apparatus will be held at two different initial angles, and therefore travel at two different speeds immediately before fracture.  Such an investigation provides important information in estimating the risk of bone fractures as a result of a direct impact at various speeds.  The central hypothesis of this lab is that the speed of the pendulum immediately prior to impact will not influence the fracture energy of the surrogate Popsicle sticks and the fracture energy of bone samples.
