曲线运动演示仪的设计

The Instrument for Curvilinear Motion Demonstrative Device

曲线运动是在高中物理必修二的教学中的一个重点和难点,学生缺乏清晰的物理图像是重要原因之一。基于磁性画板原理,设计了一种新的曲线运动演示仪器,在绘制曲线运动轨迹的同时,准确确定落球点。这将有助于在教学中让学生观察到实验现象,分析实验规律,从而提高物理教学效率。

Curvilinear motion is a key and difficult point in the teaching of the physics in senior high school. The most important reasons is the lack of clear physical images for students. Based on the principle of magnetic Sketchpad, a new curvilinear motion demonstration instrument is designed in this paper, which not only draws the curve trajectory, but also accurately determines the drop point of the ball. This will be helpful for students to observe the experimental phenomenon and analyze the experimental law in order to improve the efficiency of physics teaching.
