Yadda ake samun hanzari? Menene dabara wanda ake lissaftawa da sauri?

  • Komai ya dogara da sashen sashen kimiyyar lissafi da kake ciki. Preari daidai, har ma a faɗi: a wane ɓangaren makanikai.

    I. Kinematics.

    a) hanzarta tare da motsi na rectalinear daidaituwa.

    Don nemo hanzarin tare da motsi rectalinear gabaɗaya, ya isa a yi amfani da dabara

    a = v / t

    inda

    hanzari;

    v girman girman canji cikin sauri;

    t lokaci (canjin lokaci).

    ko dabara

    a = (v v0) / t

    inda

    hanzari;

    v ƙarshen gudu na jiki;

    v0 farkon jikin mutum;

    t lokaci.

    b) haɓakawa yayin motsawa cikin da'ira.

    Don nemo hanzarin lokacin da ake zagaye da'ira, mafi yawancin lokuta ana amfani da dabara:

    a = (v ^ 2) / r

    inda

    haɓakar ɗaruruwa;

    v tsananin gudu na jiki;

    r shine radius na da'ira.

    Amma akwai wasu dabaru:

    a = 4 * (^ 2) * r / (T ^ 2)

    inda

    haɓakar ɗaruruwa;

    r da'ira;

    T lokacin zagayawa cikin jiki;

    = 3,14159265 ...

    a = 4 * (^ 2) * r * (^ 2)

    inda

    haɓakar ɗaruruwa;

    r da'ira;

    sauyin jiki;

    = 3,14159265 ...

    a = (^ 2) * r

    inda

    haɓakar ɗaruruwa;

    tururuwa na yau da kullun na jiki;

    r shine radius na da'ira.

    II. Darfafawa.

    A cikin kuzari, haɓaka yana bisa ga dokar ta biyu ta Newton.

    Newton's dokar ta biyu kamar haka:

    Yadda ake samun hanzari? Menene dabara wanda ake lissaftawa da sauri?

    Tsarin dokar 2-th na Newton shine kamar haka:

    a = F / m

    inda

    hanzari;

    F karfi (girman karfi);

    m nauyi.

  • Daga hanyar kimiyyar lissafi sanannu ne: Haɓaka jiki yayin haɓaka motsi ɗaya daidai yake, rabo na canjin sauri zuwa tsawon lokacin da wannan canjin ya faru. Dabarar ita ce: a = v-v0 / t (hanzarta shine saurin canji a saurin jiki).

    Takenarfafa motsi mai daidaituwa gaba ɗaya ana ɗauka azaman rukunin hanzari a cikin SI, a inda saurin ya canza ta 1m / s don 1 s. Mitan murabba'in kilomita na 1 a sakan na biyu.

    Hanzartawa yana da yawa na vector, ana rarrabe shi ba kawai ba koyaushe ba, har ma da shugabanci.
