Analysis of the Possibility of Achieving the Purpose of Newton’s Second law Experiment Presented in the 2015 Revised Curriculum Physics I Textbooks

This study was conducted to determine if Newton’s second law experiment presented in the 2015 revised curriculum physicsⅠ textbooks can achieve the purpose of the experiment. For this purpose, Newton’s second law experiments presented in eight kinds of physicsⅠ textbooks were classified based on the method used to apply a force to an object, and experiments were performed to obtain real data. As a result of the study, all textbooks will have difficulty in deriving the desired goal from the textbook when the currently presented method is used. Specifically, in the experiment using elastic force, a specific method for constant external force needs to be proposed. In addition, in the experiment using the gravity of weight, it seems to be necessary to consider the error from the frictional force. In conclusion, we need to carefully examine if the experiments in the textbook can achieve their purposes. In particular, performing experiments involving Newton’s second law is difficult; therefore, it is necessary to consider what is the best way to deal with Newton’s second law experiment in a textbook.
