Homerwork Science (20/08/2017) WHAT IS ENERGY? AND TYPES OF ENERGY The energy is abality to do some work. All things need energy to move, for example: The car uses energy from the oil and gas for its movement. There are several types of energy, for example: Electric energy such as light bulbs; heat energy such as the bonfires;  muscular energy of our body to move things ; the energy that comes from the sun is the solar energy; the energy of water is the hydel energy; the wind energy which produces electricity. Energy can be stored, por example: Sunlight is stored in the solar panels in the day and at night gives light to the light bulbs.

Homework Science (20/08/2017) Types of Energy The energy is abality to do a work. There are several types of energy, for example: The energy that is found in food, when we eat we have the energy to walk and work; the solar energy which we receive in the form of heat and light; the street light use electrical energy to see in the dark; the kinetic energy is the energy due to movement; the potential energy is the energy stored inside the object, t he gravitational energy that is the movement produced by the force of gravity. “Energy can neither be destroyed nor created but it can transform from one form of energy to another”, for example the potential energy can be to transform into kinetic energy.  Electrical energy is transformed into heat and light It’s important to keep in mind: The plants use solar energy for photosynthesis. Only 10% of the energy of the bulbs is for light, the remaining 90% is heat.
