Two different rivers have drops that are the same height. In river A, this section of the river is a waterfall in river B, this section has a hydroelectric dam. In what way does the energy differ between the drops in the two rivers
The energy differs in the form in which it is harnessed. In river A, the energy from the drop is in the form of potential energy (due to the elevated height), and it is converted into kinetic energy as the water falls down the waterfall. In river B, the energy from the drop is harnessed by the hydroelectric dam and converted into electrical energy.
