What is energy? Laws of energy. Forms of energy. Sources of energy. Types of energy. Using and saving energy.
Energy is the ability to do work. Energy is found everywhere in the world and comes in many forms.
“Energy is neither created not destroyed. It changes from one form into another” “ You can´t see energy, you just can see it´s effects or the changes it produces”
There are two forms of energy: Potencial energy: the energy stored. Chemical energy as the one in batteries is an example of potential energy. Kinetic energy: Is the energy in motion.Thermal energy and wind energy are some examples of kinetic energy.
TThere are two main sources of energy : renewable and non-renewable sources of energy.
Renewable energy is the energy that we can reuse over and over again, wind, water, sunlight… Non-renewable energy is the one that is produced from animals and plants remains and it needs million and million of years to replenishes.
Types of energy: Electrical energy: is the energy produced by the flow of electric change. Chemical energy: is the energy produced by fossil fuels and biomass. In our bodies, it is the energy produced by the food we eat. Mechanical energy: is the energy produced by things in motion. Thermal energy: is the energy released as heat.
Nuclear energy: is the energy found in chemical elements, like uranium and plutonium. Light energy: is the energy found in light, mainly the sunlight.
We can save energy: Using efficient electric bulbs. Closing the window when the heater is on. Opening the window when there is sunlight. Closing the tap when we are brushing our teeth. Recycling paper.
