Pengembangan Alat Praktikum Tumbukan Menggunakan Mikrokontroler, Sensor Ultrasonik, dan Lintasan Air Track
Momentum is one of the physics topics that students can better understand with practical activities.The problem found in using the ticker timer as a speed gauge in the collision practicum is that the measurement process interferes with the system being measured.This research develops a collision practicum tool using a microcontroller and ultrasonic
