And you know me – it had to be a projectile made of water.
The shopping mall where I live has some really nice water features that I always get fascinated by, so I had to share. My favorite one is the fountain in the picture below (and if it is too hard to see in the pictures, there is a movie at the bottom of this post).
In the picture below, for example, you see a moment where the water has stopped, but there is still quite a lot on its way.
You can watch it falling, and you see that on the right, the next burst is starting.
What I find so fascinating is that the short bursts of water visualize the trajectory so much more clearly than a continuous stream of water does, and also than a flying ball would. It almost gives the impression of being slow motion, even though of course it is not.
If I were to teach introductory physics any time soon, I would make a really nice teaching unit out of this one. But for now I’ll leave you with a movie:
