Question

What is the gravitational potential energy of a `10 kg` object on a shelf `14 m` high?

Answer 1

1372 Joules

Explanation:

Potential energy is given by

P.E = Mass (m) * Acceleration due to gravity (g) * Height (h)

Here mass is 10 kg., height is 14 meters and assuming

`g=9.8`, Potential energy is `10*9.8*14` i.e.

1372 Joules
