Question

What kind of energy is possessed when water stored in the reservoir of a hydroelectric dam.

Answer 1

1. The energy possessed by a body on account of its position or configuration is called potential energy.
2. $$\begin{gathered} PotentialEnergy=mass\times accelerationduetogravity\times height \\ \therefore P.E.=m\times g\times h \end{gathered}$$
3. Hence, potential energy is possessed when water is stored in the reservoir of a hydroelectric dam.
