Question

Calculate the missing term. Consider the value of g as 10 m/s2
m = 12 Kg h = 13 m GPE =? (Take g = 10 m/s2)

  1. 1560J
  2. 156J
  3. 15.6KJ
  4. 1560 KJ

hintHint:

When the m is 12 Kg, h is 13 m, and g is 10 m/s2, the GPE is 1560 J.

The correct answer is: 1560J


    • The gravitational potential energy is calculated as GPE= mgh.
    • When m is 12Kg, h is 13m, and g is 10 m/s2, the GPE can be calculated as the multiplication of the m,g, and h.
    • Thus, mgh= 12x 13x 10= 1560, and the GPE is calculated in Joules. Hence, GPE= 1560 J.
