Energy is everything that cause movement, we found energy in every kind of form that you can imagine, when you eat, your body receive alot of energy making us work faster, when we receive energy from the sun by radiation, the principal founds of energy are kinetic and potential energy. Kinetic energy is energy that is in movement, example: releasing the arrow from the bow, potential energy is energy that is stored on an object, example: water on the top of the waterfall. Energy can't be destroyed or created, it can only be transformed. Mechanical energy is when an object have both, potential and kinetic energy at the same time, example:a moving car. Chemical energy this energy is form by diferents chemical reaction, example: wood burning. Electrical energy when every electricity give light and heat, example: lightning. Gravitational energy is the motion caused by gravity, example: water that is pulled down a waterfall.
