受空气浮力影响的称重实验

Weighting Experiments Affected by Air Buoyancy Force

物体的质量和重量是否与运动速度有关?是否与带电状态有关?为什么陀螺旋转起来后"重量"会变轻?为什么电容器充电后"重量"会变轻?为什么气球充电后会向上飘?实验物体体积增加,导致空气的浮力增加,是产生称重变化的原因。物体的质量和重量与运动速度无关,与带电状态基本无关。

Do the mass and weight of an object have something to do with its moving speed？ Do they have something to do with its charged state？ Why a top＇s weight decreases with its rotating speed？ Why a capacitor＇s weight decreases with its charges？ Why a balloon goes up after charged？ The volume increase of these objects resulting in the increases of air buoyancy force is the reason of changes in weighting.The mass and weight of an object have nothing to do with its moving speed,little to do with its charged state.
