IS THE DIFFERENCE BETWEEN WASTE ENERGY AND DESTROY ENERGY???

Energy is fascinating human from millions of year. Fire is very important discovery in the history of mankind after the discovery of fire our life change dramatically.

We daily listen about energy in our daily life. We take food to get energy then one question is arising that what is energy?

Energy is nothing but a source which gives us capacity to do work. Some get energy from flesh or meat and someone get energy from green plant. But overall without energy we can’t do any work even breathing.

Now come on point how energy creates and how energy lost. It is very interesting  to note that energy can neither be crated nor be destroy but it change one form to another. When we rub our hand the kinetic energy change into heat energy. bulb became hot befour glowing means heat energy change into light energy when heat energy come from sun it it used by solar panel to change heat energy to chemical energy and the battery convert chemical energy into electrical energy.

Now it is clear that energy is neither be not created nor be destroy only change one form of energy to other.

Now we are going to understand some basic concepts of energy.

If I give you a bullet to through on wall of the classroom is any change occur no there will no change now do same experiment take that bullet and fired it from gun to the wall the wall will damage.

Can you gas why this happens?

This is happen because when bullet is fired from the gun the bullet has more energy and when we through the bullet from hand the bullet get less energy do you know why? This is due to velocity now I am going to introduce the term kinetic energy

What is kinetic energy?

It is a type of energy in which energy is posses by the motion of the object. In mathematics we can write the equation of kinetic energy

                                          k.E =1/2mv²

Now the form of energy is potential energy you always see that water tank is always above the surface do you know why?

water tank of gidhaur 

 Now we understand the concepts of potential energy

What is potential energy?

The energy posses by its position are called potential energy. It is depend on the distance between the earths and object called height it is also depend on the gravity also. Mathematically we can write it

                                       P.E= M×g×h

There is also various form of energy which we come across in our daily life like gravitational energy, nuclear energy, thermal energy, wind energy, tidal energy, etc.

we know that energy can neither be created nor be destroy then why government tells to save the energy it is the question can you guess the answer ? please think 
government tells us to save energy because energy production cause so much pollution and a lot of money is require to change the energy one form to another so government say to us to save the energy and its also our duty to don't waste energy.
so we should use word don't waste the energy not don't destory the energy because no one can destroy the energy from universe accept god!!!!!!
