Energy: The interconversion and its various forms
Hi steemians! I am here to share some knowledge about transformation of energy and its various forms. I hope you will like this post.
ENERGY is an important and fundamental concept of science. A body possesses energy if it is capable of doing work. It links almost all the natural phenomena. Water running down the stream has the ability to do work. Its energy can be used to run water mills and turbines.
- Law of Conservation of Energy:-
Energy can never be destroyed however it can be converted from one form to another form. It is called law of conservation of energy. For example rub your hands together quickly. You will feel warm. You have used your muscular energy in rubbing hands, as a result heat is produced. During this process mechanical energy is converted into heat energy.
- Form of Energy:-
Energy exists in many forms such as
- Mechanical energy
- Heat energy
- Sound energy
- Electrical energy
- Chemical energy
- Nuclear Energy
- Mechanical energy:-
Moving air is called wind. It drives windmills and pushes sailing boats. Thus, a moving boat has some energy because it can do work due to its motion. " The energy possessed by a body both due to its motion and position is called kinetic energy".
- Heat energy:-
Heat is a form of energy given out by hot bodies. The sun is the main source of energy. The food we take provides us energy to carry out life activities. Large amount if heat is obtained by burning coal. - Electrical energy:-
Electrical energy is one of the widely used form of energy. We can get electrical energy from batteries and electric generators. These electric generators are run bu hydro power, thermal or nuclear power. - Sound energy:-
Sound is produced by a vibrating body. Vibration means to and fro motion of a body such as vibrating diaphragm of drum and vibrating string of sitar. - Light energy:-
Plants produce food in the presence of sunlight. We get light from candles, bulbs etc. - Chemical energy:-
Chemical energy is present in food, fuels and in other substances.Electrical energy is obtained from electric cells and batteries as a result of which a chemical reaction among various substances takes place. - Nuclear energy:-
Nuclear energy is the energy released in the form of nuclear radiations in addition to heat and light during nuclear reactions.
This is a good basic explanation, but the "sound energy" is actually the same with "mechanical energy" because sound is also caused by the kinetic movement of particles, the only difference is the frequency of such movement.
