g = 10m/s²
Fg = mg → m = Fg / g
m = 52N / 10m/s² = 5,2kg
m = 5,2kg
2. 0,65kN to chyba ciężar tak?
Fg = 0,65kN = 650N
g = 10m/s²
Fg = mg → m = Fg / g
m = 650N / 10m/s² = 65kg
m = 65kg
kg= N: g
kg= 52N : 10m/s²
kg= 5,2 kg
Odp. Masa tego ciała wynosi 5,2 kg.
0,65 kN = 650N
kg= 650N : 10 m/s²
kg= 65 kg
Odp. Masa tego pojemnika wynosi 65 kg.

g= przyspieszenie ziemskie ( 10 m/s²)
N= kg* m/s²
