Various forms of energy and their interconversion

Various forms of energy and
their interconversion
magnetic energy
mechanical energy
heat energy
light energy
chemical energy
electric energy
sound energy
nuclear energy
- the energy possessed by iron or steel to
attract 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 interacts
with magnetic enegy and changes into
electric energy
- definition
- with the exception of energy in fuels, all
forms of kinetic and potential energy taken
together
- muscular energy
- posessed in the muscles of animals
- example-a mixi grinding something
- inter-conversion
- when an electric drill is used to bore a hole
in a wooden block, smoke starts rising-
mechanical to heat energy
- when two stones are rubbed together-
mechanical to light energy
- the energy which causes the sensation of
warmth or coldness
- when the heat changes the water to steam
in a pressure cooker, the steam lifts the
weight on top of the lid and whistles
- this shows that heat energy has the
capability of doing work
- inter conversion
- in steam engines- heat changes into
mechanical energy
- preparation of chemical compounds-heat
changes into chemical energy
- the energy which causes the sensation of
vision
- when a strong beam of light falls on fine
dust then the dust moves
- this proves that light energy is capable of
doing work
- inter-conversion
- when light falls on silver salts coated on
photographic plates- light to chemical
energy
- it is a kind of hidden energy in the atoms of
elements or compounds
- chemical energy of petroleum changes into
heat energy as we use it
- inter-conversion
- in chemical energy changes into electric
energy
- the energy which is produced due to the
movement of electrons in good conductors
- used for running electric fans
- inter-conversion
- in electric fans- mechanical energy changes
into electric energy
- the energy causes the sensation of hearing
- when an object breaks the sound barrier
the buildings will fall
- this proves that sound energy is capable of
doing work
- when we speak in front of
microphones-sound to electric energy
- the energy holding the nuclear particles
within the nucleus of an atom
- when the nucleus of a heavy atom like
uranium or plutonium is smashed it
releases nuclear energy in the form of heat
or light energy
