The angathe munda magetsi, ubale mphamvu ndi kuthekera

Taganizirani ubale mphamvu ndi mphamvu m'munda magetsi. Tiyeni tinene tiri ndi thupi zabwino mlandu. thupi ili wazunguliridwa ndi munda magetsi. Fast kutsogolo kwa munda ndi mlandu abwino kulanda zomwe anagwira ntchito. Ukulu wa ntchito zoterezi ndi mwachindunji njila kwa kukula mlandu ndipo malingana ndi malo ake m'munda wa kusamutsidwa. Ngati timatenga chiŵerengero yangwiro ntchito A Mtengo wa anasamutsa mlandu Q, ndiye kufunika ubwenzi A / Q sadzakhala amadalira kuchuluka mlandu umene anasamutsidwa, koma azidalira pa kusankha mfundo kayendedwe, kumene mawonekedwe njira sikuthandiza.

Tiyeni atchule mlandu m'munda, kusuntha izo kwa mfundo wamphamvu lakutali, munda mwamphamvu ndi ziro. Kufunika kwa ubale wa ntchitoyi ndi kuchita nthawi yomweyo ndi mphamvu ya m'munda magetsi a, ndi kuchuluka kwa woyang'anira amene anasamutsidwa azidalira yekha pa gulu lomaliza la malo mfundo. Motero, phindu ili ntchito kuti mufotokozere poipa kwambiri za phula pa.

Phindu limene kuwayeza chiŵerengero cha ntchito anachita mu kutengerapo mlandu zabwino pa makamaka munda kufika osawerengeka ndi kuchuluka mlandu umene umayenda akutchulidwa lingathe kumunda.

tanthauzo Izi zikutanthauza kuti ina m'munda ndi wofanana ndi kuthekera, amene anachita kupita mlandu zabwino pa mfundo opatsidwa osawerengeka.

Ukulu wa lingathe amaimira kalata φ:

φ = A / Q

Angathe - kuchuluka scalar. Zoyenereza pa mfundo iliyonse ya m'munda ndithu mlandu thupi mtengo zabwino, ndi zimphamvu za thupi ndi mlandu zoipa ndi mtengo negative.

Timasonyeza kuti kucheza ntchito ndalama, umene anachita mu kutengerapo mlandu zabwino ndi kuchuluka kwa woyang'anira anasamutsidwa ndi wofanana ndi kuthekera mfundo kusiyana kuyenda.

kusiyana ulipo pakati pa mfundo ziwiri zosiyana za kuthengo, motero, amatchedwa mphamvu m'munda pakati pa mfundo zimenezi. Ngati voteji munda wotchedwa U, ubale pakati pa mphamvu ndi kuthekera amalifotokoza aone kuti pali kuti:

U = φ₁ - φ₂

Mu tanthauzo limeneli, angathe wamphamvu kutali yomwe kukhala wolingana ndi ziro. Pankhaniyi tinganene kuti angathe kufika ziro kungakhale mfundo zongopeka zakutchire, kusankha kwake kwathunthu ochiritsira. Kusiyana angathe mfundo ziwiri owonjezera a m'munda zimadalira pa mfundo osankhidwa a ziro angathe.

Mu maphunziro ongolankhula ndale mfundo zochita angathe wamphamvu lakutali mfundo. Komabe - Msikiti padziko lapansi.

Choncho, angathe sayansi - ndi phindu kuwayeza chiŵerengero ntchito kulanda mlandu zabwino pamwamba mu ina ya kuthengo ukulu wa mlandu.

Kubverana mavuto ndi kusonyeza lingathe khalidwe la munda magetsi. Komanso, ngati maganizo ndi mphamvu zake khalidwe ndi kudziwa kuchuluka kwa mphamvu amene amachita pa mlandu mu wopondereza ina ya munda, kuthekera - mphamvu yake khalidwe. Ndi zimphamvu mwa mfundo zosiyanasiyana tingadziwire ukulu wa kumunda magetsi ntchito apitirira kuyang'anira ntchito njira:

A = qU, kapena A = Q (φ₁ - φ₂),

momwe Q - mlandu wambiri, U - munda voteji pakati pa madontho ndi φ₁, φ₂ - kuthekera mfundo kusamutsidwa.

Taganizirani ubale wa pakati mwamphamvu ndi kuthekera mu umodzi munda magetsi. Mwamphamvu E iliyonse ya munda womwewo, ndipo potero mphamvu F, amene amachita pa mlandu wagawo, kwambiri, chomwecho ndi wofanana E. Tidziwanso kuti mphamvu zomwe amachita pa mlandu Q m'munda umenewu adzakhala wofanana F = qE.

Ngati mtunda pakati pa mfundo ziwiri za munda ndi wofanana ndi anthu d, adzapereke ikukwaniritsa kusuntha ntchito:

A = Fd = gEd = ga (φ₁-φ₂),

kumene φ₁-φ₂ ndi kusiyana ulipo pakati pa mfundo kumunda.

Choncho:

E = (φ₁-φ₂) / D,

mwachitsanzo yunifolomu magetsi kumunda mwamphamvu adzakhala wofanana ndi kusiyana kuthekera zomwe kugwa pa kutalika wagawo chimene chinachitika pa mzere wa mphamvu ya m'munda.

Pa mtunda yaing'ono, kugwirizana mphamvu ndi kuthekera limanenedwa chimodzimodzi ndi m'munda nonuniform, kuyambira m'munda wanu uliwonse pakati pa mfundo ziwiri kwambiri spaced angathe kumwedwa kwa yunifolomu.
