新媒体技术对我们的日常生活和物理教学越来越重要。在新媒体实验工具研究项目的范围内，我们在物理教育中使用新媒体实验工具进行实验，并研究它们对学生学习能力的影响。我们希望展示智能手机作为一种特殊的新媒体设备的可能性，它可以作为课堂物理实验和日常生活中的工具。在本文中，我们概述了使用这些简单易用的日常工具来确定引力加速度作为物理学中最基本的参数之一的不同方法。实验的理论背景从简单使用万有引力定律到恢复系数，涉及不同的物理概念（力学和声学）。因此，每个实验都需要不同的前提条件，并且可以通过完全不同类型的学习者（高中和大学水平）进行这些实验并确定课堂物理中最基本的参数。
New media technology becomes more and more important for our daily life as well as for teaching physics. Within the scope of our N.E.T. research project we develop experiments using New Media Experimental Tools (N.E.T.) in physics education and study their influence on students learning abilities. We want to present the possibilities e.g. of smartphones as special new media devices serving as tools for conducting experiments in classroom physics and in daily life as well. In this paper, we give an overview about different methods for determining the gravitational acceleration as one of the most fundamental parameter in physics by using these easy-to-have and easy-to-use everyday tools. The theoretically backgrounds of the experiments range from the simple use of the law of gravitation to the coefficient of restitution and refer to different physical concepts (mechanics and acoustics). So each of these experiments requires different pre-conditions and it’s possible to conduct these experiments and determine this most fundamental parameter in classroom physics by completely different types of learners (high-school as well as college level).
