Detailed explanation-1: -Running water is not an example of potential energy.
Detailed explanation-2: -The water drop has gravitational potential energy because of its height in the gravitation field. Likewise, the object carrying a net positive charge has electric potential energy because of its height.
Detailed explanation-3: -At the top of the waterfall, the water is higher in the gravitational field of the Earth and has gravitational potential energy. When it falls, the potential energy turns into kinetic energy.
Detailed explanation-4: -The running water primarily possesses potential energy.
Detailed explanation-5: -A raised weight. Water that is behind a dam. A car that is parked at the top of a hill. A yoyo before it is released. River water at the top of a waterfall. A book on a table before it falls. A child at the top of a slide. Ripe fruit before it falls.
