=types of energy:=


 * Kinetic energy** is energy of motion. A rubber band flying through the air has kinetic energy. When you are walking or running your body is exhibiting kinetic energy.**Potential energy is converted into kinetic energy**. Before the yo-yo begins its fall it has stored energy due to its position. At the top it has its maximum potential energy. As it starts to fall the potential energy begins to be changed into kinetic energy. At the bottom its potential energy has been converted into kinetic energy so that it now has its maximum kinetic energy. A waterfall has both potential and kinetic energy. The water at the top of Bridal Veil Falls has stored potential energy. When the water begins to fall, its potential energy is changed into kinetic energy. This change in energy also happens at Niagara Falls where it is used to provide electricity from the transformation of mechanical and electromagnetic energy to parts of the northeastern United States.

WHAT IS ENERGY? energy is the ability of an object to do work. types of energy:

KINETIC heat light sound electrical wind water

POTENTIAL electrical gravitational nuclear chemical mechanical biomass

HYDRO ENERGY

hydro energy is water moving through a turbine. the biggest producers of hydro energy is Canada, the second largest producers of hydro energy is U.S.A, the third largest producers of hydro energy is china.

when the water moves through a turbine the turbine spins a generator and creates electricity.

RENEWABLE AND NON-RENEWABLE ENERGY renewable energy is energy that can be used over and over again. non-renewable energy can't be used again.

SOLAR ENERGY solar energy is very dependent on the weather.

GEOTHERMAL ENERGY geothermal enery is water getting pumped deep underground, the water turns into steam and pushes a turbine.

WIND ENERGY wind energy uses wind to power a turbine, the wind turns the turbine and generates electricity.
