Question

Tutorial on energy :)

Answer 1

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 \(Heat \space is \space a \space form \space of \space energy \).

gr8 tutorial @jiteshmeghwal9

Answer 8

thaanx !

Answer 9

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

Answer 10

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!

Answer 11

Thanx @Vincent-Lyon.Fr sir :)

Answer 12

thats pretty cool great jobb

Answer 13

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

Answer 14

awesome job :D
