Find the energy possessed by an object of mass \(10\ kg\) when it is at a height of \(6\ m\) above the ground. Given, \(g\ =\ 9.8\ m s^{–2}\).

The formula to calculate the potential energy is,

\(Potential\ energy\ =\ Mass\ (m)\ \times \frac{Acceleration\ due\ to\ gravity\ (g)}{Height\ (h)}\)
\(Potential\ energy\ =\ Mass\ (m)\ \times Acceleration\ due\ to\ gravity\ (g)\ \times Height\ (h)\)
\(Potential\ energy\ =\ \frac{Mass\ (m)}{Acceleration\ due\ to\ gravity\ (g)}\ \times Height\ (h)\)

Potential energy \(=\) \(J\)
