Pengembangan Alat Eksperimen Tumbukan Dengan Menggunakan Sensor Optik Dan Sen…

The number of students who do not understand collision and momentum learning material because the learning system is still the lecture method, resulting in a lack of student interest and learning interest. Based on this, this study designed a device that can investigate the value of gravitational acceleration (g), coefficient of restitution (e), potential energy (EP), kinetic energy (EK), a…
