| Popis: | 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 sensor as a distance recorder. The glide track used is an air track. Based on the research conducted, it can be concluded that the collision practicum tool with a microcontroller and a glide track in the form of an air track can work well. The distance recorder or DRD is capable of recording distances every 0.2 seconds. The ultrasonic sensor as a gauge has an accuracy of 99.6% and a relative error of 0.56% for sensor 1. Meanwhile, sensor 2 has an accuracy of 99% and a relative error of 0.85%. Through the distance data obtained, it is possible to obtain an increase in momentum before and before the collision. |
