Základné definície: Hybnosť a Impulz sily

Hybnosť (p) je definovaná ako súčin hmotnosti telesa (m) a jeho rýchlosti (v): $p = m \cdot v$.

Impulz sily (I) je definovaný ako zmena hybnosti, teda $I = \Delta p = F \cdot \Delta t$, kde $F$ je sila a $\Delta t$ je čas, počas ktorého táto sila pôsobí.

Príklady výpočtu hybnosti (p)

1. Hybnosť auta

• Hmotnosť: $m = 1000 \text{ kg}$
• Rýchlosť: $v = 90 \text{ km/h} = 25 \text{ m/s}$
• Výpočet: $p = m \cdot v = 1000 \text{ kg} \cdot 25 \text{ m/s} = 25\,000 \text{ kg}\cdot\text{m/s}$

2. Zmena hybnosti vlaku

• Hmotnosť: $m = 30 \text{ ton} = 30\,000 \text{ kg}$
• Počiatočná rýchlosť: $v_1 = 50 \text{ km/h} \approx 13.89 \text{ m/s}$
• Konečná rýchlosť: $v_2 = 80 \text{ km/h} \approx 22.22
