oblicz energię potencjalnom ciała o masie 50g podniesionego na wysokość 500m
(g=10m/s do potengi drugiej)
m = 50 g = 0,050 kg
h = 500 m
g = 10 m/s^2
zatem
Ep = m*g*h = 0,05 kg *10 m/s^2 * 500 m = 250 J
==============================================
m= 50g = 0,05kg
Ep= m*h*g
Ep= 0,05kg*10N/kg*500m=250J
