随着科学技术的发展,数码照相在人们的生活中普遍得到应用.数码照相克服了普通照相需要冲胶卷、洗印照片的麻烦,照片可以随时在数码相机或电脑上查看,也可以在投影仪上让学生观看.这对于在物理教学上研究匀加速运动的图像十分方便,有利于学生理解匀加速运动.1实验目的(1)初步掌
With the development of science and technology, digital photography has been widely used in people’s life.Digital photography overcomes the inconvenience that ordinary photography needs to print film and print photos. The photos can be viewed on a digital camera or a computer at any time, and can also be displayed on a projector Let the students watch.This is very convenient for studying the picture of uniform acceleration in physics teaching, which is good for the students to understand the uniform acceleration.1 Experimental purposes (1) The initial palm
