Glossary of Terms
Hydro Power: power obtained from the natural movement of masses of water. The moving water has kinetic energy that is used to power an electrical generator. The turning of the generator transforms the waters kinetic energy to electricity.
Kinetic Energy: the energy possessed in an object as a result of its motion. The kinetic energy of the object is equal to one-half of the product of its mass times its velocity squared (KE= ½ mv2)
Grid: a system of interconnected power lines and generators that is managed so that the generators are dispatched as needed to meet the requirements of the customers connected to the grid at various points. The utility network of transmission and distribution lines used to distribute electricity from power plants to consumbers.
Kilowatt (kW): one thousand watts, where a watt is a unit of electrical power calculated as the rate of energy transfer to one ampere flowing under a pressure of one volt. Ten 100 watt light bulbs use one kilowatt (kW) of electric power.
Velocity: the rate of position over time, calculated by dividing distance by time.
