Internal or inherent power; capacity of acting, operating, or producing an effect, whether exerted or not; as, men possessing energies may suffer them to lie inactive., Power efficiently and forcibly exerted; vigorous or effectual operation; as, the energy of a magistrate., Strength of expression; force of utterance; power to impress the mind and arouse the feelings; life; spirit; -- said of speech, language, words, style; as, a style full of energy., Capacity for performing work.
It comes from a Greek word meaning activity.
And that's not a bad beginning, because except for potential energy, all energy is the motion of something ... even if its just the energy itself (as in photons).
So everything is either matter or energy ... and either one can be changed into the other.
Energy is measured in Joules in the SI system. Any type of energy can be assessed in Joules. Heat is measured in calories or BTU, but can be put into Joules by the mechanical equivalent of heat, which is 4.2 Joules per calorie, or1055 Joules per BTU.
The most basic definition of the Joule is the work done in moving 1 meter against a force of 1 Newton
It is a phrase used to advertise sugary food and drink, by confusing the separate meanings of the word 'energy'.
One type of energy is the chemical energy in the sugar, which is used in the body to produce force from the muscles, but it also produces obesity.
The other meaning of 'energy' is the feeling of being energetic and vital. The advertisers hope you will accept that meaning and not think of the other one above.
Energy means power which may be translated into motion, overconing resistence, or effecting physical change, and its ability to work.
Energy basically is the potential of doing work. The rate of use of energy is the rate of doing work. The work can be mechanical, electrical, or thermal.
pooooooooooooooooooooooooooooooooooooooooooooooooooooop
That he or she has energy 😒duu
Technically gravity is always working so it cannot be potential, I would say that if anything it is kinetic. The influence that gravity has on everything gives that object potential energy.
an example of a energy pyramid is say for example theres a continuous light protected by a line spectrum it automatically gives energy to the energy pyramid.
When we say that energy is lost in a resistor, it really means that electrical energy has bee transformed into other forms of energy. These other forms of energy do not easily get changed back into electrical energy.
Mechanical energy is heat light and kinetic energy but instead of saying something has heat light and kinetic energy we just say mechanical! :)
Well some say food some say the sun.. When really its both! The sun gives off light which plants take in through a process called photosynthesis. Because of that photosynthesis the plants can grow! The people and animals eat the plants and get energy. Remember when you hungry, then have something to eat? All of a sudden you feel way better? thats because you got energy from what ever you ate.
the food which we eat gives the energy to the brain---------------------I cannot agree with this one. This would mean that if we eat the same food, then we all should have the same brain energy. This is not the case never mind what we eat.Definitely there is something else that gives the energy to our brains. I'd say that our brain cells are capable of acquiring the energy from universe. So, different cells bind different energy and that's how we are different.How that process wroks, ohh, well, I'd like to learn about it too.
Yes, it gives me energy, while some say it makes them sleepy.
well for starters lets say banana's are an energy food that gives you the right to say answers and have a go

There you are means maybe someone was looking for you and found you and they say, "There you are". it also expressed when someone gives you something; example; your mom brings cookies to you and she says "there you are" and you say "thanks"
When we say that something is alive. we mean it has life in it.
Sort of they generate food which gives them energy so you can say yes
that something is fresh
You say you're sorry.

something you say to not have your mom kill you
He hates you
