超重与失重演示装置的改进

Improvement on the demonstration device of overweight and weightlessness

对原超重失重实验装置进行了改进,利用蓄电池和小灯泡等简易材料设计了触发电路,当重物出于失重状态时,绿灯亮;当重物出于超重状态时,红灯亮,同时灯的位置也发生了相对改变,更明确地演示了超重和失重现象.

The traditional demonstration device of overweight and weightlessness was improved. The improved device used some materials, such as accumulator and bulb, in the trigger circuit. When the object was weightless, the green light turned on; when the object was overweight, the red light turned on. With the color change of the light, its position also changed. So, the phenomena of over- weight and weightlessness were demonstrated clearly.
