# What is the gravitational potential energy of a  9 kg object on a shelf  5/6 m  high?

Feb 14, 2016

GPE = $m g h = \left(9 k g\right) \left(\frac{5 m}{6}\right) \left(10 m {s}^{-} 2\right) = \frac{450}{6}$ joules = 75 J
g = acceleration due to gravity ~10m s^-2
GPE = $m \times g \times h = \left(9 k g\right) \left(\frac{5 m}{6}\right) \left(10 m {s}^{-} 2\right) = \frac{450}{6}$ joules = 75 J
