Experiments with high-speed video recording of the fall of a pre-stretched steel soft coil spring equipped with an additional point-like weight were carried out. It is shown that the fall of a spring with a weight, as well as without a weight, has a levitation stage of the lower part of the spring and the weight. In this case, in the upper part of the spring a compression shock wave moving downward at an almost constant speed is formed. The dependence of the shock wave velocity on the weight mass is measured. The dependence turned out to be increasing, but this growth is slower than the linear dependence.

The dependence of the levitation stage duration on the weight mass was measured. The dependence also turned out to be increasing, but slower than linear. The upper limit of the growth of this dependence was not reached, but it should be assumed that its growth is limited from above, at least by the spring material plasticity limit.

The main result of the work: the added weight increases the duration of the spring levitation stage, and the greater the weight of the weight, the longer the levitation of the bodies.

进行了高速录像的预拉伸钢软螺旋弹簧跌落的实验，该弹簧装有附加的点状砝码。示出了带有重物以及没有重物的弹簧的下落具有弹簧下部和重物的悬浮阶段。在这种情况下，在弹簧的上部形成以几乎恒定的速度向下移动的压缩冲击波。测量了冲击波速度对重量质量的依赖性。事实证明依赖性增加了，但是这种增长比线性依赖性要慢。

测量了悬浮阶段持续时间对重量质量的依赖性。依存度也增加了，但慢于线性。尚未达到这种依赖关系的增长上限，但应假定其增长至少受弹簧材料可塑性极限的限制。

这项工作的主要结果是：增加的重量增加了弹簧悬浮阶段的持续时间，并且重量越大，物体的悬浮时间就越长。
