Question

The energy possessed by water stored high up in the dams is primarily KE.
(A) True
(B) False

Answer 1

Hint: Kinetic energy is the energy of mass in motion. The kinetic energy of an object is the energy it has because of its motion. Note that energy is a scalar quantity, i.e., it does not depend on direction, and it is always positive.

Complete answer: The kinetic energy of water is when it is rushing through a river, down a waterfall or through a hydroelectric power plant. The force of the kinetic energy is dependent on the height and mass of the falling water. Hydroelectric is when water is used to produce electricity.
Water stored in a dam possesses potential energy and once the water starts falling, it has kinetic energy.
So, the above given statement is true
When flowing water is captured and turned into electricity, it is called hydroelectric power or hydropower. There are several types of hydroelectric facilities; they are all powered by the kinetic energy of flowing water as it moves downstream.
Additional information: As an object falls from rest, its gravitational potential energy is converted to kinetic energy. Conservation of energy as a tool permits the calculation of the velocity just before it hits the surface. K.E. = J, which is of course equal to its initial potential energy.

Note The concept of kinetic energy was first discovered by Gottfried Leibniz and Johann Bernoulli. They described it as the 'living force'. In 1829, Gaspard-Gustave Coriolis wrote an important paper developing the concept
