Question

Determinati energia potentiala a unui corp cu masa de 2 kg care este ridicat la inaltimea de 5 m stiind ca g=10N/kg
Formula energiei potentiale: m×g×h =Lg

Answer 1

m=2 kg
h=5 m
g=10N/kg
Ep= m*g*h
Ep= 2kg*5m*10N/kg
Ep=100J
Ep=100J

Answer 2

$m=2 \ kg \\ g=10 \ N/kg \\ h=5 \ m \\ \boxed{E_p-?} \\ \bold{Rezolvare:} \\ \boxed{E_p=m \cdot g \cdot h} \\ E_p=2 \ kg \cdot 10 \ N/kg \cdot 5 \ m \\ E_p=20 \ N \cdot 5 \ m \\ \Rightarrow \boxed{E_p=100 \ J}$
