Misalan Amfani da Dokokin Newton
Dokokin Newton suna ɗaya daga cikin muhimman ginshiƙan kimiyyar lissafi, wanda Sir Isaac Newton ya yi bayani a ƙarni na 17. Ya gabatar da dokoki guda uku na asali, waɗanda galibi ake kira dokokin motsi na Newton. Waɗannan dokoki ba wai kawai suna da mahimmanci a fannin kimiyyar lissafi ba, har ma suna da amfani mai yawa a rayuwar yau da kullun da kuma fasahohi daban-daban da muke amfani da su. Wannan labarin zai tattauna wasu aikace-aikacen dokokin Newton a fannoni daban-daban na rayuwa da fasaha.
Dokar Farko ta Newton
Dokar farko ta Newton, wacce aka fi sani da dokar inertia, ta bayyana cewa:
"Wani abu zai kasance a hutawa ko kuma ya motsa a layi madaidaiciya a daidai gwargwado sai dai idan wani ƙarfin waje ya yi masa aiki."

Dokar farko ta Newton na iya danganta kai tsaye da amfani da bel ɗin kujera a cikin motoci. Lokacin da mota ta yi hatsari, jikin fasinja, wanda da farko yake tafiya tare da motar, yana ci gaba da tafiya gaba saboda rashin ƙarfin jiki. Ba tare da bel ɗin kujera ba, jikin fasinja zai ci gaba da motsi har sai ya haɗu da abin tsayawa, kamar allon mota ko gilashin mota, wanda zai iya zama mai mutuwa. Bel ɗin kujera yana ba da ƙarfin waje da ake buƙata don dakatar da jiki da rage haɗarin rauni.

Sitika masu rataye a bango suna nan a wurinsu domin babu wani ƙarin ƙarfi da ke shafar motsinsu. Idan iska mai ƙarfi ta faɗa maka ko ƙura ta taruwa ta kuma sha danshi, waɗannan ƙarin ƙarfi na iya sa sitika ta fita.
Dokar Newton ta Biyu
Dokar Newton ta biyu ta bayyana cewa:
"Yawan hanzarin da abu ke samarwa yana daidai gwargwado kai tsaye da ƙarfin da ke aiki a kansa kuma yana daidai gwargwado da nauyin abu."
A lissafi, ana iya rubuta wannan doka kamar F = ma, inda F shine ƙarfi, m shine taro, kuma a shine hanzari.

Dokar Newton ta uku ta bayyana cewa:
"Kowane aiki koyaushe yana da martani iri ɗaya da akasin haka."
Wannan yana nufin cewa idan abu A ya yi ƙarfi a kan abu B, abu B kuma yana yin ƙarfi daidai gwargwado amma akasin haka akan abu A.
