Motion Uniform kunye neempawu zayo

Phakathi ezahlukeneyo lweentshukumo, ezifana wafunda icandelo yemvelo, njengoko yeefom, kukho enjalo apho umzimba ukuba naziphi na amathuba lokungavinjwa ezikhethiweyo ezilinganayo kwexesha ziqwempu alinganayo ngobude bendlela. Oku - motion efanayo. Umzekelo ukuhamba emkhenkceni phakathi ku-kude ngololiwe okanye a elula flat.

Isondlo, umzimba Ungasa ecaleni nayiphi na indlela, kubandakanywa egosogoso. Kulo mzekelo, kukho ingqiqo ngendlela - ngoko umgama ohanjiweyo ngumzimba kweyalo indlela. Indlela - a ubuninzi scalar, kwaye mazingabhidaniswa neeMviwo zeSatifikethi seMatriki intshukumo. Igama yokugqibela ibonisa lekhefu phakathi kwindawo yokuqala kunye umendo zokugqibela ityhalela wegophe ngabom ayifuni ungqamane isikhokelo. - Iindawo ezinika umdla ubungakanani kumda wesangqa ukuba lixabiso lenani elingana nobude kumda wesangqa.

Lo mbuzo ubangelwa - kwezinye iimeko sithetha isindululo efanayo? Kuya kuthathelwa ingqalelo i isindululo efanayo, efana okuvezwa kwisangqa nesantya efanayo? Hayi, ngenxa yokuba loo Velocity motion kumda wesangqa utshintsha lwayo njalo.

Omnye umzekelo - imoto sihamba kumgca othe ngqo ngesantya esifanayo. Loo isindululo uya kuthathwa uniform, lo gama i imoto akayi kuqengqeleka phezulu kwaye isantya oko inani elifanayo. Ngokucacileyo, intshukumo efanayo kusoloko kusenzeka kumgca othe ngqo, kumda wesangqa Velocity akawatshintshi. Indlela kunye nentshukumo efanayo kulo mzekelo uya kuba njalo.

intshukumo Uniform - zentshukumo yophuhliso kumgca othe ngqo ngesantya esingaguqukiyo, apho ubude endleleni ababehamba amathuba nayiphi na ngamathuba ixesha rhoqo ziyafana. Ityala ekhethekileyo sesindululo uniform nga zizakujongwa njengo imo yokuphumla, xa isantya kwaye umgama ohanjiweyo ilingana zero.

Isantya ubunjalo iimpawu iyunifom motion. Licacile elokuba, izinto ezahlukeneyo enye nendlela enye ngexesha eyahlukileyo (ngeenyawo kunye imoto). Sengqondo egubungele imizimba ngokufanayo lisiya ubude bexesha apho umendo lidlule, ebizwa isantya intshukumo.

Ngenxa yoko, ifomula echaza isindululo uniform, imi ngolu hlobo lulandelayo:

V = S / t; apho V - uqina (a ubungakanani kumda wesangqa);

S - okanye ihamba umendo;

t - time.

Ukwazi isantya, leyo rhoqo, sinako ukubala umendo onqamlezwa umzimba ngalo naliphi na ithuba ngokwesigqibo esicalanye ixesha.

Maxa wambi ngempazamo ezixutywe ngokulinganayo kwaye ngokufanayo olukhawulezisiweyo eshukumayo. Lo gama eyahlukileyo ngokupheleleyo. Nombala ekhawulezayo motion - omnye sazo sesindululo olungalinganiyo (.. Ie ukuba apho isantya njalo), nto leyo eye inkalo ebalulekileyo - isantya esinjalo isiphakamiso uyohluka amathuba efanayo kwixabiso efanayo. Eli xabiso lilingana umahluko Velocity ozalanayo ubude bexesha apho utshintsho isantya kuthiwa kokuba unikezelo. Eli nani ebonisa isixa-mali ngayo isantya inyuswe okanye ihliswe ngeyunithi nganye ixesha lingaba likhulu (ngoko bathi umzimba ukuzuza ngokukhawuleza okanye ukulahlekelwa isantya) okanye okungenamsebenzi xa into ibalekisa okanye uyehla ngaphezulu kamnandi.

Lunikezelo ngokunjalo Velocity na inani elibonakalayo wesangqa. Ukukhawuleziswa kumda wesangqa kweli cala isoloko ingqamana kumda wesangqa Velocity. Umzekelo motion ngokufanayo olukhawulezisiweyo kunjalo na ukuwa lwe sifundo, apho isantya owela (isantya umphezulu umdla into emhlabeni) kuyahlukana ngokuya ixabiso ethile ebizwa yokunyusa ukuwa xa iyunithi ixesha.

intshukumo Uniform kuthiwa zijongwe kwityala okhethekileyo ngokufanayo okukhawulezileyo. Ngokucacileyo, ekubeni ngesantya isiphakamiso eso akawatshintshi, unikezelo okanye deceleration ayenzeki, ngoko, ixabiso kukukhawuleziswa ngexesha isindululo uniform isoloko ilingana zero.
