The Falling Chain Analysis Using Kitchen Scales
Nuryadin, Bebeh Wahid
Physics Education, v55 n3 Article 035024 May 2020
This research aims to develop a falling chain experiment apparatus using kitchen scales and digital cameras (smartphones). Digital cameras were used to observe and record changes in the mass of falling chains measured using kitchen scales. Video recordings from observations of falling chain masses were analysed using Tracker 5.1.1 software. The observations show that the change in chain mass measured by kitchen scales has three main patterns of motion. The first pattern is a linear measurement, where an increase in the mass of a falling chain is measured three times higher than its actual mass. Then, the second is damped oscillation motion when the needle scale oscillates with an amplitude that continues to decrease with time. The damped oscillation movement caused by the use of springs (and air friction) as the primary system of mass measurement, so the kitchen scales need time to show the exact mass measurements (stable pattern). This experiment hopefully makes it easier for the student to understand some of the concepts of physics, especially the concepts of force, object mass, time, kinematics, momentum (impulse), and damped oscillations, through experiments at home, school, or university.
