За \(\mathrm{\Delta}\)t
\(V_{A}\) > \(V_{Б}\)
\(\angle\ \gamma_{А}\) = \(\angle\ \gamma_{Б}\)
\(\overline{V}\) = \(\frac{l}{t}\) – линейная скорость
\(\omega\) = \(\frac{\varphi}{t}\) – угловая скорость
\(\omega\) – угловая скорость
\(\varphi\) – угол поворота
[\(\omega\)] = \(\frac{рад}{с}\) = \(с^{- 1}\)
l = \(\varphi\) · R
V = \(\omega\) · R
[Т] = c
T = \(\frac{t}{N}\)
N – количество оборотов
Т – период
v («ню») = \(\frac{1}{Т}\) = \(\frac{N}{t}\)
[v] = \(с^{- 1}\) = Гц
\(\omega\) = 2\(\pi\)v = \(\frac{2\pi}{T}\)
\(a_{ус.}\) = \(\frac{V^{2}}{R}\) = \(\frac{\omega^{2}R^{2}}{R}\)
