What is energy ?
The theory defines that Energy is just a form of work that we do(In our daily life).
Scientists explained energy a Quantity if physics. Energy is just a thing that we can feel sometimes but can observe in the form of work. for example if i create a great amount of pressure on your hand you can feel it but can't measure that on the behalf of feelings(ah that sound a bit funny😀..).
Now if we talk about work ,we can observer the work .
example :- if i push a table ,i can see that i did the work of pushing so that position of table has changed. And we can measure that work or energy in the quantity of joule or any other respective unit.
According to Einstein we can relate energy with mass ,The huge mass relate to huge energy and less energy relate to less mass.
light is an electromagnetic radiation and it has no mass so we can not divide it in kinetic energy and potential energy as well.(If you want to know the meaning of this line please read carefully and complete the law and types of energies as described below.)
Energy conservation law:-
we know that energy conservation law states that we can not create energy or we can not destroy the energy. Humans are just able to transform energy from one form to another form.
we have listened about various energy.
But i am telling you we can distribute all type of energy in the three forms :-
1.Potential energy
2.Kinetic energy
3.Combination of both the energies
we can not categories dark energy because dark energy is a hypothetical type energy but there are some theories so that we can divide it into kinetic or potential form.
Different types of energies :-
1.Heat energy:-
we can transfer this energy from one object to another object by taking the difference in temperature.
And it is a combination of partly kinetic energy and partly potential energy.
2.Electrical energy:-
Because the motion of the charge particles we can call it is a kinetic energy but on the other hand , we can consider it on different perspective that we can also store electric field as field lines in capacitor.
3.Mechanical energy:-
for example :-It consists potential energy of the object and the kinetic energy of the motion of the object.
4.Light energy:-
Light is a energy which a form of electromagnetic radiation. Light consists a lot photons ,and when an object' atoms heat up photons are produced. Light is a form of energy which is visible to human.
generally , Light energy can not penetrate the wall and some other materials also.
And light is an electromagnetic radiation and it has no mass so we can not divide it in kinetic energy and potential energy as well.
similarly, we can not describe dark energy in the term of potential and kinetic energy.
