Design And Build A Practicum Equipment For The Law Of Conservation Of Mechanical Energy Of Rolling Objects

Using photo gate sensor technology and digital displays, the research team created a legal practicum for energy conservation. This study aims to replace manual equipment that is prone measurement errors during practicum. used prove law of conservation mechanical in rolling objects. Practicum developed using development process starts with identifying needs continues through design, manufacturing, testing. At design stage, validation results carried out, while at manufacturing testing stages, specifications performance (measurement accuracy precision) are out. Based on validation, value 0.85 valid category was obtained, 90.7%, an average 97.46%, relative error 8.33%. The thoroughness objects quite good. We currently developing several pieces IoT-assisted smartphone displays.
