Two different rivers have drops that are the same height. In river A, this drop of the river is a waterfall. In river B, this drop has the generator for a hydroelectric dam. In what way does the energy of the water differ between the drops in the two rivers? (1 point)
• The kinetic energy of the water would be less at the bottom of the drop in the waterfall river A than at the hydroelectric dam river B.
The potential energy of the water would be less at the top of the drop in the waterfall river A than at the

The kinetic energy of the water would be greater at the bottom of the drop in the waterfall (river A) than at the hydroelectric dam (river B).
Reason: the potential energy at the top is the same for both (same height). At the dam much of the potential energy is extracted as electrical energy, so the water leaving the turbine has less kinetic energy than water that simply falls in a waterfall.
