Zákony zachovania

Last updated 14 Dec 22 Edit Source

$$E_{k} = \frac{1}{2}mv^{2}$$
$$E_{p} = \int_{\vec{s}}{F \cdot \vec{s}} = Fs\cos\alpha = mgh$$

$$p = m\vec{v}$$
$$\vec{F} = \frac{\Delta\vec{p}}{\Delta{}t}$$
$$\vec{I} = \vec{F} \cdot \Delta{}t = \Delta{}p$$

$$\sum p = C$$

Tieto zákony (hybnosť a enenrgia) sa dajú aplikovať na zrážky:
$$m_1v_1 + m_2v_2 = m_1v_1' + m_2v_2'$$
$$v_1 + v_1' = v_2 + v_2'$$

Relativistická hmotnosť
$$m = \frac{m_0}{\sqrt{1 - \frac{v^{2}}{c^{2}}}}$$

$$E - E_{0} = E_K$$
$$\frac{m_{0}c^{2}}{\sqrt{1 - \frac{v^{2}}{c^{2}}}} - mc^{2} = E_K$$
