Thiết kế và sử dụng bộ thí nghiệm khảo sát chuyển động nhanh dần đều trong dạy học Vật lí 10

Tóm tắt

The 2018 Physics general education program is approached in the direction of developing learners' competence, accordingly the program emphasizes the role of experimental and practical activities in the process of forming concepts, rules and laws of physics. “Uniformly accelerated motion” is an important and core knowledge in the subject “Kinematics” in grade 10. Currently, the uniformly accelerated motion experimental set equipped in educational institutions still has certain limitations, causing difficulties for teachers in the process of using it for teaching in class. The study proposes a design plan for a uniformly accelerated motion experimental set to overcome some limitations of the existing experimental set in high schools. The uniformly accelerated motion experimental set is designed based on the application of Arduino microcontroller, obstacle sensor and tilt angle sensor. The experimental results show that the acceleration values obtained through the self-made experimental set give results consistent with the theory with an error of less than 5%.
