Question

Calcule a energia potencial gravitacional nos casos abaixo, utilizando g = 10 m/s2:
(A) m = 200 kg; h = 10 m → EG = __________ J.
(B) m = 30 kg; h = 8 m → EG = __________ J.
(C) m = 40 kg; h = 5 m → EG = __________ J.
(D) m = 4 kg; h = 10 m → EG = __________ J.
(E) m = 0,5 kg; h = 4 m → EG = __________ J.

Answer 1

Formula: EG = mhg

(A) EG = 20000 J
(B) EG = 2400 J
(C) EG = 2000 J
(D) EG = 400 J
(E) EG = 20 J
