【设计理念】目标让学生清楚,过程让学生参与,结论让学生得出,规律让学生发现,收获让学生交流。【设计课题】自由落体运动。【学习目标】1.知道物体只在重力作用下从静止开始下落的运动,叫做自由落体运动。条件是物体仅受重力作用从静止开始下落。2.知道重力加速度g就是自由落体运动的加速度,方向竖直向下,在地球不同地方重力加速度的大小不同,通常情况下取9.8m/s2。 [Design Philosophy] The goal is to make the students clear, the process allows the students to participate, the conclusions let the students draw, the rules allow the students to discover, and the harvest allows students to communicate. [Design topic] Free fall movement. [Learning Objectives] 1. Knowing that objects only fall from rest under gravity is called free-fall motion. The condition is that the object will fall from rest only by gravity. 2. Know that the gravitational acceleration g is the acceleration of the free-falling body movement. The direction is vertical downwards. The gravitational acceleration is different in different parts of the earth. Generally, it takes 9.8m/s2.
