Starting the project
In the class of Physics we have learned that the Energy is the property of the material systems that can effect changes in it selves or in the enviroment.
Some examples of Energy are :
A rock in the top of a mountain ; gravitatonial Energy
The sun ; thermic Energy
A spring ; elastic Energy
Food ; chemical Energy
The unit for Energy is the Joule (J). The conversion factor for other units are:
1 calorie is 4,19 J
1 Kilowatt is 3,6 x 106 J
1 ton is 4,13 x 1010 J
