Pengaruh Massa Jenis Kelereng Terhadap Koefisien Restitusi Sebagai Rancangan Lembar Kerja Peserta Didik Materi Momentum Berbantuan Phypox

Abstract

This study aims to analyze the effect of the density of marbles on the coefficient of restitution in the event that marbles fall freely to the floor using the Phyphox application on a smartphone, and to design student worksheets on momentum material. The research using experimental methods. Data and research result are displayed in the form of tables and graphs. The result showed the coefficient of restitution increases logarithmically when the density increases and the design of student worksheets on momentum material contains experimental activities to analyse the relationship between the density of marbles and the coefficient of restitution in free falling marbles using the Phypox application on smarthphone.
