Mechanical, Electromagnetic, Electrical, TYPES OF ENERGY Mechanical, Electromagnetic, Electrical, Chemical and Thermal
What is energy The ability to do work or cause change The energy can take a wide variety of forms - heat (thermal), light (radiant), mechanical, electrical, chemical, and nuclear energy. There are two types of energy - stored (potential) energy and working (kinetic) energy. For example, the food you eat contains chemical energy, and your body stores this energy until you release it when you work or play.
How is energy stored? All forms of energy are stored in different ways, in the energy sources that we use every day. These sources are divided into two groups -- renewable (an energy source that we can use over and over again) and nonrenewable/conventional (an energy source that we are using up and cannot recreate in a short period of time). Renewable energy sources include solar energy (which comes from the sun and can be turned into electricity and heat), wind energy, geothermal energy (from inside the earth), biomass from plants, and hydropower from water are also renewable energy sources.
How do we use energy? We use all these energy sources to generate the electricity we need for our homes, businesses, schools, and factories. Electricity "energizes" our computers, lights, refrigerators, washing machines, and air conditioners, to name only a few uses. We use energy to run our cars. The gasoline we burn in our cars is made from oil. We use energy to cook on an outdoor grill or soar in a beautiful hot-air balloon. The propane for these recreational activities is made from oil and natural gas. Energy is in everything. We use energy to do everything we do, from making a jump shot to baking our favorite cookies to sending astronauts into space -- energy is there, making sure we have the power to do it all.
What is Mechanical Energy? Energy due to a object’s motion (kinetic) or position (potential). The bowling ball has mechanical energy. When the ball strikes the pins, mechanical energy is transferred to the pins!
Examples of Mechanical Energy
What is Electromagnetic Energy? Light energy Includes energy from gamma rays, xrays, ultraviolet rays, visible light, infrared rays, microwave and radio bands
What is Electrical Energy? Energy caused by the movement of electrons Easily transported through power lines and converted into other forms of energy
What is Chemical Energy? Energy that is available for release from chemical reactions. The chemical bonds in a matchstick store energy that is transformed into thermal energy when the match is struck.
Examples of Chemical Energy
What is Thermal Energy? Heat energy The heat energy of an object determines how active its atoms are. A hot object is one whose atoms and molecules are excited and show rapid movement. A cooler object's molecules and atoms will show less movement.
