Question

# Calculate the missing term. Consider the value of g as 10 m/s^{2}

m = 12 Kg h = 13 m GPE =? (Take g = 10 m/s^{2})

- 1560J
- 156J
- 15.6KJ
- 1560 KJ

Hint:

### When the m is 12 Kg, h is 13 m, and g is 10 m/s^{2}, 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/s
^{2}, 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.

^{2}, the GPE can be calculated as the multiplication of the m,g, and h.### Related Questions to study
