Various forms of energy and their interconversion

magnetic energy

- the energy possessed by iron or steel toattract or repel iron like substances

- when a magnet attracts iron towards itself

- this proves that it is capable of doing work

- inter-conversion

- in electric generator- mechanical interactswith magnetic enegy and changes intoelectric energy

mechanical energy

- definition

- with the exception of energy in fuels, allforms of kinetic and potential energy takentogether

- muscular energy

- posessed in the muscles of animals

- example-a mixi grinding something

- inter-conversion

- when an electric drill is used to bore a holein a wooden block, smoke starts rising-mechanical to heat energy

- when two stones are rubbed together-mechanical to light energy

heat energy

- the energy which causes the sensation ofwarmth or coldness

- when the heat changes the water to steamin a pressure cooker, the steam lifts theweight on top of the lid and whistles

- this shows that heat energy has thecapability of doing work

- inter conversion

- in steam engines- heat changes intomechanical energy

- preparation of chemical compounds-heatchanges into chemical energy

light energy

- the energy which causes the sensation ofvision

- when a strong beam of light falls on finedust then the dust moves

- this proves that light energy is capable ofdoing work

- inter-conversion

- when light falls on silver salts coated onphotographic plates- light to chemicalenergy

chemical energy

- it is a kind of hidden energy in the atoms ofelements or compounds

- chemical energy of petroleum changes intoheat energy as we use it

- inter-conversion

- in chemical energy changes into electricenergy

electric energy

- the energy which is produced due to themovement of electrons in good conductors

- used for running electric fans

- inter-conversion

- in electric fans- mechanical energy changesinto electric energy

sound energy

- the energy causes the sensation of hearing

- when an object breaks the sound barrierthe buildings will fall

- this proves that sound energy is capable ofdoing work

- when we speak in front ofmicrophones-sound to electric energy

nuclear energy

- the energy holding the nuclear particleswithin the nucleus of an atom

- when the nucleus of a heavy atom likeuranium or plutonium is smashed itreleases nuclear energy in the form of heator light energy
