Energy is something that we need to do work and activities. Energy can be grouped into some groups:
1. heat Energy
It is something we have always used to heat ourselves up and usually released by sources of light energy.
2.light Energy
Light energy is a type of energy that have given our eyes the ability to see . Light energy are found on things that give out light , and almost all of light energy sources also releases heat energy
3.Kinetic Energy
This is a kind of energy that is found on moving things or things that have velocity.mathematically we write as;
Kinetic Energy=0.5 x M x v x v
Where M is mass and v is velocity
4.electrical energy
A kind of energy that we use very much nowadays to power up our electronic things .
5.atomic energy
Energy that is stored within a thing's atom . If this energy is accumulated in big amount. It can create disastrous consequences if it isn't use correctly .e.g. Nuclear bomb.
Mathematically if all mass is about to turn into energy , we write it as:
Energy=MCC
Where M is mass and C is the speed of light.
That formula is created by Albert Einstein
6. Potential energy
An energy stored in a thing or an energy that is gained by things because of its position. Potential energy is divided into 3 large group:
A. Potential gravity energy
An energy stored by a thing because of its position, usually things that Is in higher position will have higher potential energy
B.potential chemical energy
An energy stored in things because the existence of chemical in that thing.
C.potential elastic energy
An energy stored in things because of their elasticity and how far they are stretched
That is all I can tell you. If you see any tense mistake or other mistakes , you may send it to jowillianto@gmail.com
Finally , I apologize for any problems and inconvenience cause by my writing and tenses
