TRANSFORMATION OF ENERGY

TRANSFORMATION OF EnergyEnergy exists in many different forms. One form of energy can be changed into another form.

The change of one form of energy into another form of energy is known as transformation of energy.

There are many examples of transformation of energy:-

• A ball held at height has only potential energy. When the ball is released from a height, then the potential energy of the ball is gradually transformed into KINETIC ENERGY.

• In fun-fair ride called Pirate Ship. Kinetic energy is changed into potential energy and back into kinetic energy.

• A high Dive an example of transferring potential energy of the diver into kinetic energy.

Examples of transformation of energy

Hydroelectric energy

In Hydroelectric power house, Potential Energy is transformed into Kinetic Energy and then into Electrical Energy.

Hydroelectricity is the term referring to electricity generated by hydropower, the production of electrical power through the use of the gravitational force of falling or flowing water.

This can be written as:- Potential energy Kinetic Energy Electrical Energy

Energy transformation at Hydroelectric Power House

Water has lots of potential energy but as such this potential energy Is of no use to us. If however water is aloud to fall from this great height , the potential energy of water changes into kinetic energy. The kinetic energy of falling water is used to drive huge turbines which are connected to electricity generators for producing electricity.

Thermoelectricity

The Thermoelectricity is the electricity which is produced when chemical energy is converted to heat energy and then to Kinetic Energy And electrical energy.

This Can be written as:-Chemical Energy Heat energy Kinetic Energy Electrical Energy

Energy Transformations at a Thermal Power House

At a Thermal power House , Chemical Energy Of Coal of changed into heat energy, Which is further converted into Kinetic energy and Electrical Energy.
