What is the significance of sqrt {2gh} ? • Physics Forums 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
