Q. HOW MANY FORMS OF ENERGY ARE THERE?
ANS. I think there are only 4 forms of energy type at fundamental level, as described below:
1. Relativistic Mass & Kinetic Energy : Which is sum of Kinetic Energy and Rest mass energy.
So Relativistic Energy = K.E.+ Rest Mass Energy = 1/2 x m0v2 + m0c2
= mc2
It is also given by
2. Potential Energy : Which is due to interaction of a particle with other particles or fields.
There are various types of potential energies, e.g. Gravitational, Electromagnetic, Nuclear etc.
3. Dark Energy : Which is as the name suggest we are not able to understand at all. We don't know what is its nature, what is its source, how it convert from one form to other forms. Only thing that we know about the Dark Energy is that, it is there. Whenever we see a change in total energy of a system without any reason it may be due to Dark Energy being converted to other known forms of energy or vice-versa. E.g. Our universe is accelerating, means our K.E. is increasing and we are not able to explain it pointing towards Dark Energy.
