    Question Momemtum or moment?

    I have read both definitions but I still donít see the difference clear to me; could you help me with a couple of examples? Thanks.

    MOMENTUM
    Symbol p Physics A measure of the motion of a body equal to the product of its mass and velocity. Also called linear momentum.(plural = momenta)
    MOMENT
    A brief, indefinite interval of time.

    However, in Portuguese, they both are 'momento'

    Designada pelo sŪmbolo P, o momento ť uma medida fŪsica: massa vezes velocidade. E momento, mesma palavra, estŠ relacionada a tempo.

    As an engineer I can answer for the momentum transfer (fluid mechanics), as for the magnetic moment...well...haha...

    I am not sure I get you. What is different?

    I guess the dear fellow delapoma thought that 'moment' could be related to 'momentum' once in his mother-tongue, they are both spelled 'momento'. So, I am telling they are quite different from each other:

    a) moment (interval of time)
    b) magnetic moment (a vector)
    c) momentum (related to mass and motion of a body)

    PS: I am not sure, English is not my first language, but I think I heard someone say: This is our momento, meaning something used as a reminder to remember (of course) someone that something (usually good) happened in the past. The teachers could clarify this for us.

    Thanks

    Hi

    Memento is sometimes spelled momento, perhaps by association with moment. The word is actually related to remember.

    In classical mechanics, I = mv
    m: mass (scalar variable)
    v: velocity (vector)
    I : a vector
