Yes, I know most of the people would be wondering that Energy?? whats new?? To be frank I haven´t formulated a new theory but I have really fascinating stuff unearthed through my BOZO friend who just doesn´t understand Physics.
Energy is according to most Physics textbooks ¨The ability to do work.¨ Now someone may ask what is work exactly? Then let me say this to some people´s irritation that work is said to be done in mechanics when a body is displaced under the influence of an unbalanced external force in the direction of force. Now isn´t that something difernt than your usual perception of work, which is getting sucked up at office!! 😉 well its a physics definition of work. Coming back to Energy, in physics we have many theories and laws regarding energy. Energy is ´generally´ of two types viz. Potential i.e. stored in a body due to its peculiar position and Kinetic i.e. energy stored in a body as a virtue of its velocity. We may easily say a stretched spring has more potential energy than a relaxed one or a body moving fast has more energy than an identical body moving at a slower speed. All these is Governed by following simple equations which is
Energy E = F*d where F is the force applied and d is the displacement in that direction. This equation is for potential energy. Mind you its a concise form.
You can compute kinetic energy with this equation… Energy E = mv*v/2. Where m is the mass of the body concerned and v is its velocity.
yes I know you´d be too familiar with these equations and definitions to be interested. But the point I´m trying to make is that science right now, can calculate, Quantify and even transform energy (thats bit lame). But can it explain WHAT Exactly/Abractly or Really Energy is?? Most people don´t ask this. But my Bozo friend did.
This happened yesterday when he came up to me and asked ¨Hey you Mr. know-it-all, can you explain me Energy?¨ I was really irritated, to be honest, as I was between my work. Nevertheless I took him up.
I explained energy Physically with formulae and examples and what not. Ultimately he said ¨But this same as what I read in the textbook. I want to know what energy is ´really´.¨ I got his point. And I was stumped. My whole foundation of physics was being questiond by this BOZO. However, I know he was right. I can´t explain energy. None can. At most anyone can say is ¨Energy is….simply energy.¨ or some might repeat this ¨Energy is the capacity to do work.¨. But None really can explain satisfactorily what energy is really. You can try..
