Thawj ntawm peb txoj cai ntawm kev txav chaw tsim los ntawm Newton (1642-1726) hais tias txhua yam khoom nyob rau hauv ib lub xeev ntawm kev txav mus los tseem nyob hauv lub xeev tshwj tsis yog siv lub zog sab nraud. Qhov no yog qhov tseem ceeb ntawm kev hloov kho ntawm Galileo lub tswv yim inertia.
Leej twg tsim qhov sib npaug ntawm kev txav?
EQUATIONS OF MOTION DISCOVERED BY ISSAC NEWTON. YOG 3 TUG EQUATIONS OF MOTION: v=u + at.
3 qhov sib npaug ntawm kev txav yog dab tsi?
Peb Qhov Kev Sib Tw ntawm Kev Sib Tw yog v=u + at; s=ut + (1/2) at² and v²=u² + 2as thiab cov no tuaj yeem muab tau los ntawm kev pab ntawm lub sijhawm nrawm nrawm siv cov ntsiab lus acceleration.
Thaum twg Galileo nrhiav tau kinematics?
In the 17th century, Galileo Galilei (1564–1642) thiab lwm tus tau pom tias, hauv qhov tsis muaj dab tsi, txhua yam khoom poob muaj qhov nrawm nrawm, thiab yog li lawv cov lus tsa suab yuav raug txiav txim los ntawm kev siv txoj cai Merton.
5 qhov sib npaug loj yog dab tsi?
Kev tsim kho ntawm qhov koj tau kawm txog tam sim no thiab qhov Galileo tau nthuav tawm, peb muaj qhov kuv tus kws qhia ntawv physics, Glenn Glazier, nyiam hu rau Tsib Qhov Kev Sib Tw Dawb Huv ntawm Kinematics kom nrawm nrawm. Hauv cov kab zauv no, v yog nrawm, x yog txoj haujlwm, t yog lub sijhawm, thiab a yog acceleration. Nco ntsoov, Δ txhais tau tias hloov pauv hauv.
