Jatuh bebas tanpa kecepatan awal, Vo = 0
Massa benda, m = 2 kg
Percepatan gravitasi, g = 10 m/s²
Tanya ;
Energi mekanik, Em = __?
Jawab :
Step 1
---------
Cari dulu Ep = ___?
Ep = m.g.h
Ep = 2•10•2
Ep = 40 J
Step 2
---------
Dan cari Ek = __?
Ek = 1/2.m.Vo²
Ek = Nol
Step 3
----------
Jadi Em = __?
Em = Ep + Ek
Em = 40 + 0
Em = 40 J
