3. Newtonov pohybový zákon

Tretí Newtonov pohybový zákon, akcie a reakcie hovorí: Ak hmotný bod A pôsobí na hmotný bod B silou f2 , pôsobí hmotný bod B na hmotný bod A silou f1 , ktorá má rovnakú hodnotu ako sila f2, a leží so silou f2 v rovnakej priamke, má však opačný smer. Je teda vždy:

f1 = -f2

Vzťah f1 = -f2 nevyjadruje však úplne obsah zákona akcie a reakcie, nevyjadruje, že sily f1 a f2 pôsobia v spoločnej priamke.
Aby sme aj túto okolnosť mohli vyjadriť nejakou rovnicou, zavedieme si na tomto mieste pojem moment sily vzhľadom na bod. Momentom sily f, pôsobiacej v nejakom bode A, vzhľadom na bod 0 budeme nazývať vektorový súčin:

D = r. f

Kde r je polohový vektor pôsobiska A sily f vzhľadom na bod 0.
Pre súčet momentov síl f1 a f2 , ktorými na seba pôsobia naše telesá A a B, vzhľadom na ľubovoľný bod dostávame:

r1. f1 + r2. f2 - r1. f2 + r2. f2 = (r2 – r1). f2 = 0

lebo vektor r2 – r1 = r12 je so silou f2 rovnobežný.
Sily akcie a reakcie okrem vzťahu f1 = -f2 splňujú teda aj rovnicu r1. f1 = -r2. f2 , alebo ak tieto momenty označíme D1 a D2, rovnicu:

D1 = -D2

ktorá vyjadruje, že sily f1 a f2 účinkujú v jednej priamke.

The most inspiring stuff commonly is probably the most dull or boring concern. a single rooster may not be in the same woody plant strip very long, and also the pets within the pine is a kind of weight, always want to consult the next stars, the particular fowl because the plants are really hesitant to facial expression an equal beautiful places day by day.
I wish more authors of this type of content would take the time you did to research and write so well. I am very impressed with your vision and insight. wwe smackdown games for pc

The website is looking bit flashy and it catches the visitors eyes. Design is pretty simple and a good user friendly interface.
