Intshukumo Mechanical - yonke into ngayo

Kubonakala ngathi igama elithi "intshukumo ngoomatshini" uthetha ukuba ngokwayo. Le ndaba ngaxa lithile, yaye emva kwethuba wazifumana kwenye - ukuba lo mbutho. Noko ke, asingabo bonke elula kangaka. Ngexesha elithi, ngasentla, kukho intsingiselo enzulu.

Ukuya ukusuka kwindawo ukuya kwindawo ayikho lophanyazo, yaye kukho nexesha elithile. Yaye kanye kanye ukusuka kwindawo A noqondo B, kwaye eminye imigca. ukuhamba umgca yomzimba ekuthiwa isikhokelo kunye ubude bayo - abadlulayo. Chaza indlela yokuziphatha kwe umzimba kunye necala eya ngakulo amaninzi kakhulu umsebenzi onzima. Kodwa ukuba sisebenzisa nokumelwa komzimba isithuba ngoncedo zilungelelanise kwexesha, kuya kuba umthetho sentshukumo.

Ngoku umbuzo olandelayo - indlela kakuhle intshukumo mechanical? Kwimeko apho zonke ezihamba kwindawo enye into, oko kuya kuba ngokuqhubekayo. Ukuba, ke, amanqaku zakhe umzimba ihambe zifumaneka kwi kwisangqa, intshukumo ejikelezayo. Apha siye sele abe neempawu sesindululo ngoomatshini, yaye akukho namnye.

Umsebenzi kuyinto inkcazo nje kuphela kwinkqubo intshukumo, kodwa ke kwingqikelelo apho umzimba bekuya kuba ngexesha elinikiweyo. Nangona kunjalo, ukuthatha eli thuba lalo mthetho sesindululo kunye neempawu zayo, kufuneka sibe nako ukufumana sisiqalo nxamnye eya kwenziwa zonke iintlawulo. Xa ichazwa, sizakugqiba inkqubo reference apho uyakwazi ukuchaza nayiphi na intshukumo ngoomatshini.

Ukutshintshelwa lwenzeka kwi ekuqaleni indawo nokulungelelanisa inkqubo okanye, ngamanye amazwi, isakhelo ireferensi. Point of imvelaphi ukuba zikhethwe lokungavinjwa, kwaye xa utshintsho ingongoma reference inkcazo isindululo ukucima omnye. Ngenxa yoko, siye sizimisele ukuba motion ngoomatshini lilinganiselwe. Le mbono ka laliqulunqwe yi UGalileo.

Ukuze ukuchaza nangokobungakanani inkqubo lonke ezihambayo, qhubeka nangoku ufake into efana isantya. Ngaphantsi oko sindululo translational lulwahlulo intshukumo ogqibeleleyo kunye nexesha elichithwa kule ntshukumo. Kwimeko apho izinga ayitshintshi ulwalathiso ixabiso layo, intshukumo noba kwaye tye. Ukuba le mfuneko ayifikelelwanga - i-intshukumo iya kuba kolwabelo olungalinganiyo.

Meaning Isantya - nokuba uyazixabisa isalamane, kwaye ixhomekeke indlela yayo, ngamanye amazwi, Le ubungakanani kumda wesangqa. Ukuba uloliwe ihambisa xa kuthelekiswa ngaphezulu komhlaba kunye ngesantya V1 kwaye kuyo kwicala uloliwe na umkhweli kunye V2 uqina, ngoko ngokuphathelele umhambi ihlabathi iza kuhamba ngesantya of V1 + V2. Ke ukuba uthe uya kuhamba nxamnye isindululo uloliwe, ngoko ngokuphathelele umhlaba, Uya kuhamba ngesantya V1 - V2.

Ukugqibezela inkcazo unit intshukumo yokulinganisa kufuneka lisetyenziselwe iimpawu. Ixesha ilinganiswa kwimizuzwana, umgama ohanjiweyo - ngeemitha, kakuhle, isantya, ngokulandelelanayo, ngeemitha ngomzuzu.

Ngaphezu siye saxubusha ingqiqo intshukumo ngomatshini ukusuka kwindawo imbono ye physics. Noko ke, le nto ifumaneka kwezinye zenzululwazi. Ngoko, igama elithi "intshukumo ngomatshini kwenani labemi," isebenza -manani zentlalo-qoqosho. Elinye igama le kota - yokufuduka. Oku kubandakanya ukuhanjiswa zabantu kummandla ngamnye (ilizwe, kwiRiphabliki, izithili), kunye nentshukumo eso esidityaniswe yokutshintsha yokuhlala.

Nesixhobo ingqiqo enjalo kuthathwa, njengoko isindululo ngoomatshini, kwaye inkcazelo iimpawu zayo. Iimpawu motion - olumanyanisiweyo, isantya, umgama - nokunika uluvo jikelele kwezinto sentshukumo. Kwakhona walatha ukusetyenziswa kweekhonsepthi efanayo kwezinye zenzululwazi.
