All bodies around us work by using energy.Even our body also uses some kind of energy.so,there are two main types of energy:- 1. $$\text{Potential Energy}$$- Petroleum & food etc. are the energy that are stored in body & vehicles so the stored energy is called $$\cal{potential \space energy}$$. 2. $$\text{Kinetic Energy}$$- when a body moves, the stored energy slowly converts into $$kinetic \space energy$$. The types mentioned above were main types . now except them there are also other types of energy :- 1. $$\text{Gravitational Energy}$$-when a heavy metal is pushed downwards then it uses our own stored energy & then converts to kinetical energy.This type of energy is called $$gravitational \space energy$$. 2. $$\text{Strain Energy}$$-When something is squeezed or strained by someone than it uses its stored energy & converts to kinetical energy. This type of energy is called $$strain \space energy$$. 3. $$\text{sound energy}$$-when two persons talk through telephone & If one person says something then his voice converts to electrical energy & passes through telephone & gain converts to sound energy.This type of energy is called $$sound \space energy$$. $$\text{Meaurement Of Energy :-}$$ The unit to measure Energy is Kelvin which is named after $$\text{J.P.Joules}$$ of Manchester who was first to suggest that $$Heat \space is \space a \space form \space of \space energy$$.

Don't forget that kinetic energy can be calculated by using this formula: $\frac{ 1 }{ 2 }\times mv ^{2}$ and for potential energy is: mgh

Gravitational energy and stress energy are different forms of potential energy. Sound energy is mechanical energy: a combination of kinetic energy (medium has density and is moving) and elastic potential energy (elastic medium is compressed). You could add Electromagnetic energy to the list. It lies where E-field and/or B-field are not zero and will be carried from one place to another by an electromagnetic wave. Good job you did here!

Thanx @Vincent-Lyon.Fr sir :)

thats pretty cool great jobb

I suppose all the other kinds of energy are subsets of the main kinetic and potential energy? :) Nice job condensing the descriptions.

awesome job :D
