重力加速度是中学物理中一个非常重要的物理量,在高中物理教材中,重力加速度这一物理量是在“自由落体运动”这一节中被引入的,但教材并未对重力加速度产生的原因、重力加速度与地理位置的关系、人造卫星或宇宙飞船中的物体受重力作用产生与地面上不同的奇异物理现象,如何测量 Gravity acceleration is a very important physical quantity in middle school physics. In the textbook for high school physics, the physical acceleration of gravity is introduced in the section of “free fall motion”, but the textbook has no reason for gravity acceleration. The relationship between acceleration and geographical location, objects in an artificial satellite or spacecraft are affected by gravity, and they produce strange physical phenomena that are different from those on the ground.
