Abstract

We investigated the rolling motion of a rigid body by using a smartphone application to verify the feasibility of using the smartphone as an alternative to the traditional experimental instruments employed in schools. Rolling motion is a combination of translational and rotational motions. This study assessed whether physical quantities, such as position, velocity, and acceleration, could be analyzed by using a smartphone to collect data on such parameters. The experiments on the rolling motion of a cylindrically shaped wheel were carried out using a smartphone application called Sparkvue. The results are discussed from the perspective of the viability of using a smartphone as an alternative to the usual experimental tools.

학교 현장에서 과학실험교육의 실험기구로서 스마트폰의 이용가치를 확인하기 위하여 굴림운동을 주제로 선정하여 연구를 진행하였다. 물체가 힘을 받아 운동할 때 굴림운동은 병진운동과 회전운동이 결합되어 나타나는 운동으로서 우리는 위치, 속도, 가속도에 대한 물리량을 어떻게 스마트폰을 활용하여 데이터로 수집 및 분석할 수 있는지 조사하였다. 본 실험에서는 스마트폰과 스마트폰 어플리케이션 Sparkvue 앱을 활용함으로서 물체의 굴림 운동에 관한 실험을 하였고, 스마트폰을 일선 학교현장에서 실험도구로서 사용가능 여부와 아울러 실험 방법을 제시하고 활용 가능한 형태로 실험이 진행되었다.
