Digital experiment system of uniform circular motion with remote laboratory based on website

Abstract

Circular motion experiment is an important activity to develop the abilities of students in learning physics. The covid-19 pandemic has caused experimental activities in the laboratory don’t be carry out properly. A solution to solve this problem is to develop a uniform circular motion experiment system with remote laboratory based on website. The objective of this research was to determine the accuracy and precision of the circular motion experimental system with remote laboratory based on website. This research can be classified into engineering research, which is an activity in the design of a product that isn’t continuous. Data collection techniques were carried out in two ways, namely direct measurement and indirect measurement. The research data were analyzed by error theory and descriptive statistics. Based on the analysis of the data obtained, it can be stated from the digital uniform circular motion modelling tool with a length of 54 cm, a width of 43 cm and a height of 21 cm with an accuracy and precision of controlling a stepper motor of 99.03 % and 98.84 %. The accuracy and precision of the uniform circular motion modelling tool with a remote laboratory is close to 100%.
