日冕物理学-不同质量的物体？
这就是我想要做的，2个球会在不同的高度掉落，它们的弹跳设置为1.0，这意味着弹跳后它们会回到原来的位置。但较高的球会比较低的球下落和弹跳得更快，因此当较高的球弹起并返回到原来的位置一次时，较低的球也会完成第一次弹跳。
它们不同时弹跳一次可以吗？我只是想知道如何改变他们的速度。
到目前为止，我发现我们无法改变它们的质量，密度不会影响下降速度，设定的重力会影响两者。请问有什么解决办法吗？
this is what i'm trying to do, 2 balls will drop at different height, their bounce is set to 1.0, which means after bounce they will go back to their original position. But the higher ball will drop and bounce faster than the lower ball, so when the higher ball bounces and goes back to it's original position once, the lower ball finishes its first bounce too.
is ok that they don't bounce once at the same time? i just want to know how i can change their speed.
so far what i have found is that we can't change their mass, density won't effect drop speed, set gravity will effect both. any solution please?

较重的东西不会落得更快。无论是在现实中还是对其进行适当的模拟。我们之所以认为重的东西下落得更快，是因为空气阻力。在空气中移动的物体会受到空气的阻力，这比重物体更能减慢轻物体的速度。
所以你要么必须打破物理系统，要么实施空气阻力。
Heavier things do not fall faster. Either in reality or a proper simulation thereof. The reason why we think of heavy things falling faster is because of air resistance. Objects moving through the air have resistance from that air, and this slows down light objects more than heavier ones.
So you would either have to break the physics system or implement air resistance.
