Instead, a perfectly inelastic collision is what happens when objects stick together.

相反，碰撞发生完全是软的 当两个身体粘在一起时。

But there’s also such a thing as a perfectly inelastic collision, because... of course there is.

但也有完全非弹性碰撞这样的事情， 因为… … 当然有。

但是有一种完美的软碰撞， 因为… … 当然有。

So, it is not a collision where the objects lose all of their kinetic energy. Instead, a perfectly inelastic collision is what happens when objects stick together.

因此，这不是物体失去所有动能的碰撞。相反，当物体粘在一起时会发生完全非弹性碰撞。
