Reply to comment by othelloblack in New study examines Leonardo da Vinci's experiments on gravity by Rear-gunner

Sand and water were dripping out of the containers, and he was watching that fall, and seeing that eventually the sand and/or water would fall straight down.

But how is the container moving? It sounds like its on a flat plane

It was. He had it sliding along, and noticed that the falling sand/water didn't keep moving horizontally, but eventually moved vertically (because of gravity).

Whereas in fact it continues to move horizontally..... as well as falling to the ground. Had he noticed that, he might have preempted Newton.

Well the sand/water kept moving horizontally, but they stopped being accelerated horizontally. They still retained horizontal momentum after leaving the container.
