If elastic collisions sound bouncy, that’s because they are.

如果弹性碰撞听起来有弹性， 那是因为它们确实有弹性。

But you won’t come across elastic collisions in real life.

但你不会在现实生活中遇到弹性碰撞。

If elastic collisions sound bouncy, that's because they are.

如果你认为 弹性震荡反弹，没错。

But you won't come across elastic collisions in real life.

但是你不会遇到任何弹性碰撞 实际上。

So, now we know about both elastic and inelastic collisions.

所以，现在我们有关于两者的信息 柔软而有弹性的凹凸。

Like the conservative systems we talked about last time, in elastic collisions, kinetic energy is neither created nor destroyed.

就像我们上次谈到的剪贴板系统一样 过去，在弹性碰撞中，能量。

We also talked about the differences between elastic and inelastic collisions, and how to calculate the center of mass of a system.

我们还讨论了弹性碰撞和非弹性碰撞之间的区别，以及如何计算系统的质心。
