Yes, of course. With a little bit of time to ponder, I have a different way of explaining this. "Why was there not a directional flow... -

It depends whether the force producing the acceleration is maintained throughout the collision. For example, if you have a vertical...

Right The second part here is correct. That means that the fluid pressure at the air-water interface is sure to be one atmosphere. The...
