ENERGY
ENERGY is the ability to make work, energy can be found in many number of forms 
1.when you eat, that food gives you energy.
2.when you walk, there´s the sun that gives you energy by heat
3.when you walk by night, lamps give you electrical energy
ALSO...
There are other tipes of energy.
POTENCIAL ENERGY that is the energy that is stored inside and object.
KINETIC ENERGY that is energy that is in motion or moving like air.
 
    
                                                      BUT REMEMBER THIS....
            
                                     ENERGY CAN NETHIER BE DESTROYED
                                                  NOR CREATED BUT IT CAN 
                                 TRANSFORM FROM ONE FORM OF ENERGY


MECHANICAL ENERGY           ELECTRICAL   ENERGY       CHEMICAL ENERGY
                                                                                                                     
     potencial energy               Whenever there´s energy               energy is caused by
               +                                  it´s electrical energy                          chemical reaction         
     kinetic energy
               =
  mechanical energy
                                     
                                                 GRAVITATIONAL ENERGY          
                                                it´s the motion caused by gravity

POTENTIAL - means - energy that comes from position or condition KINETIC ENERGY                                                   POTENTIAL ENERGY                !                                                                                           ! Objects in motion                                                           Objects that are not moving Eventhough you're not moving , you have the ability to move. When you raise an object , you give it   the ability to move 1.  POTENTIAL ENERGY IS PROPPER FROM Static objects 2. EXAMPLES OF POTENTIAL ENERGY   1. A rock sitting at the edge of a cliff  2. Tree branches high up in a tree  3. A stick of dynamite 4. The food we eat 5. A stretched spring in a pinball machine

1.  If you are riding in a roller coaster as in figure 2-8 , how do you think your speed is related to your kinetic energy?your potencial energy? If i move , i'm producing kinetic energy and when the roler coaster is in the top of the base waiting to have spped enough to avance in the rest of the coaster 2.  As a roller coaster climbs to the top of the speepest hill on its track , when does the first car have the greatest potential energy? when does it have the greatest kinetic energy? when it's on the top of the rail it's like static so it's potential energy . when the coaster is falling from that part that i was talking about in the first part of the question it has the most potential energy 3. State the law of conservation of energy in your own words. It's like a easer thing for people to understand that you can not do anithing with energy , nor create it or destroy it 4.  You get up in the morning , get dressed , eat breakfast , walk to the bus stop
