Thermal energy

5. MECHANICAL ENERGYy
There are two types of energy.
Kinetic energy: This energy is produced when objects
move.
Potential energy: This energy is prouced when a object
in a equilibrium position move to another position.

6. ELECTRICAL ENERGY
This energy have relationship with electric current. Machines
only moves with an electrical suply.

7. ELECTROMAGNETIC ENERGY
The waky talky use them , are electromagnetic waves. The
waves are the means of transmision.

8. SOUND ENERGY
The mean of transmision is vibration. Like movil phones
when emit music it use sound waves

9. CHEMICAL ENERGY
This energy is extracted from chemical reactions our body get
energu by this way

10. NUCLEAR ENERGY
Energy is extracted from the nucleus of atoms. Central power
estations use this metod to obtain energy. The stars produce
this energy.

11. THERMAL ENERGY
Its pprofuce when particles are in contact the
temperature of an object its the thermal energy that it
have.

12. ENERGY SOURCES
This are natural and can provide us diferent kinds of
energy
Tow types:
Renewbable:This are sources that are unlimited like
the sun.
Non-renewbable:This are sources that are limited like
the coal.

13. WIND TURBINES
Wind turbines have long produced renewable energy but a French
engineering firm has discovered another eco-purpose for the towering
structures.

14. ENVIROMENT IMPACT
Acid rain: This is caused by the gases that react with water
vapor and produce acids and fall down to the earth.
Nuclear waste: To produce energy nuclear power stations
produce waste subtances that are very bad for our live. They
are put in nuclear cementerys.
Oil pills: When petroleum is trasnport in ships some time
they break and the petroleum kill all animals in the sea that
are there.
Water temperature: Power stations need water for refligerate
and they release then to rivers this change of temeperature
can kill fish
