1.超重现象物体具有向上的加速度,对支持物的压力(或对悬挂物的拉力)大于物体所受重力的情况称为超重现象.产生超重现象的原因:当物体具有向上的加速度a(向上加速运动或向下减速运动)时,
1. Overweight phenomenon The object has an upward acceleration, the support of the pressure (or tension on the suspension) is greater than the gravity of the object is called overweight phenomenon. Overweight phenomenon causes: When the object has an upward acceleration (upward Accelerate or slow down down movement)
