Abstract

In this research, we will learn about the concept, measurement and analysis of an impulse using a smartphone accelerometer. The impulse measurements were performed in several experimental conditions such as free-fall objects hitting a sand surface, two cars in collision and straight punching (boxing jab). During the experimental process, the acceleration of objects (such as children's toys and smartphones) is measured using a smartphone accelerometer application. Then, the acceleration versus time data were analysed to determine the impulse characteristic, such as the time interval and area of the impulse, and it was compared with the motion analysis using video (image) analysis. We hope this alternative apparatus is a valuable, low-cost and straightforward experiment for physics laboratories or sports science analysis.
