In physics, tensors are often a mixture of several vector spaces and several dual spaces. It also makes sense to sort both kinds as the tensor product isn’t commutative. Definition: A tensor of type of with contravariant and covariant components is an element (vector) of By (1) this tensor is linear in all its components. Tensor Examples

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...
