 P: 6 Hi, I'm not sure how to word my question, so I will just state it upfront. What is the importance of $$\upsilon$$ = $$\sqrt{2gh}$$ in physics? I've seen it in escape velocity problems, though with an R instead of h. I've seen it with conservation of momentum applications, and it's similar to PE = mgh. Yesterday my professor was discussing Bernoulli's equation and this equation came up again. I was just wondering how it can be applied to so many different situations...
