14实验：打点计时器测速度(国外英语资料) 14 experiment: RBI timer measuring speed.Txt, if you see the shadow before, dont be afraid, it is because you have the sun behind! I allow you to walk into my world, but never allow you to walk around in my world. High school physics classroom teaching plan day and month Topic Section 1.4: the experimental velocity measurement by RBI timer Class type New instruction (2 hours) teach learn order mark Knowledge and skills 1. understand the timing principle of the dotting timer and understand the movement information (time and displacement) of the object contained in the tape 2. install and use point timers to understand the principle of measuring speed based on tape and to measure instantaneous speed 3., make clear the physical meaning of the image at one time, describe the method of drawing pictures, and draw the speed of the experiment An image that can obtain useful information from an image Process and method 1., through the students themselves to look at the instructions of the RBI timer, to cultivate students ability to learn independently 2., the motion information of the object is obtained by experiment. It is expressed by mathematical method. It can train students to acquire information and process information Ability to understand the ways of dealing with problems and to understand how to measure indirectly the quantities of physics that cannot be measured directly 3., by drawing the speed one time image, students can use the image method to process data and experience the mathematical tools in the development of Physics The role of 4., experience the importance of rational thinking in the experiment, both to start, but also to the brain 5., through the process of scientific inquiry, to understand the significance of scientific inquiry, try to use scientific inquiry method to study object movement Emotion, attitude and values 1., feel the smart design idea of the timer, and understand the guiding role of physical principles in solving pr
