FOOTNOTES:
[A] A law is a statement of a constant mode of behavior. It is often expressed in mathematical language.
[B] The mass of a body is the amount of matter in it, the weight is the pull of the earth upon it.
[C] "Head" is a term used to express the vertical height of water in pipes.
[D] The position of a submarine in or under water is controlled in a similar manner.
