    "boundary of the billiard" or "billiard boundary" ?

    Hi,

    can you give me some general rule helping me to chose between such pairs:

    "boundary of the billiard" or "billiard boundary",
    "velocity of the particle" or "particle velocity",
    ...

    Thank you!

    Benjamin

    In most cases, I would say that the two constructions are interchangeable.

    We are travelling at the speed of light.
    We are travelling at light-speed.

    The velocity of the particle has been measured at...
    The particle velocity has been measured at...

    I am a little confused by your first example. What do you understand by "billiard"?

    Re: "boundary of the billiard" or "billiard boundary" ?

    Thank you for your reply,

    but aren't there any hints concerning the good writing style. For example, I find:

    "The velocity of the boundary of the billiard equals zero",

    somehow obscure because of the doubling of "of the", and thus inferior to:

    "The velocity of the billiard boundary equals zero."


    p.s.: My example is from physics. Billiard is a bounded domain in space where particle moves freely and reflects elastically from its boundary. Terminology arises from the analogy with the billiard table and the game of snooker.

    So do you mean "The velocity at the billiard boundary is zero?"

    Hello, emsr2d2.

    Could you enlighten me and spell out what the rare cases are in which these two forms are better considered as not interchangeable.

    If you could further enlighten me with the terms given to these two forms, it would be just great.

    Thanks in advance
