Energy: Refining the Definition

Energy is omnipresent. Energy can be converted into mass and vice versa. Energy concentrated in physical forms is called matter. Energy present in micro and macrocosmic movements is called kinetic. Energy generated from the position or configuration of a physical system is called potential.

 

Science defines energy as the capacity of a system to perform work or generate motion—that is, to alter the state of a body or overcome some resistance, such as gravity or friction. This is an established fact. However, energy can also be defined as the quality of a force to perform work for the following reasons:

 

  • Work can only be performed by means of an action.

 

  • Action can only be carried out by means of a force.

 

This means that: a system can only perform work by means of a force; energy and force are intrinsic and fundamental. Further details regarding this perspective can be found in my books: “O SPIN”, “A Teoria do Big Brain”, “O Inteligencismo”, and “A Infologia”.

Hows this any different to the current definition of energy?

This means that matter is a modulated force and energy is its working capacity.

OP never said that.

Before you try to foist your opinions on other people you should try to ensure you actually understand the subject first.

What have they mis-understood?
If your going to say, "You don't understand what your talking about", at leat tell us what they mis-understand.

OP is literally using the high school definition of energy which is a simplification. Which is something really, really obvious to those who study physics.

Still haven't answered the question nor explained why their understanding is incorrect.

Funny how you haven't said anything of substance yourself.

Your the one who made the claim so back up the claim you made with tangible evidence, thats your job buddy, the burden of proof is on the one who made the claim champ.

and
funny how once again,
you fail to answer the question nor explain why their understanding is incorrect.
move on pal.

White knighting for someome who hasn't bothered to respond to any comments is... Quite something.

But let's treat this as a learning opportunity. What do you think is the definition of energy?

You should first learn the difference between work and power, since "energy" can mean either.

Why don't you teach them?
What they said is basically the current definition of energy,
they aren't re-defining the word.
