In classical mechanics, energy is a conceptually and mathematically useful property, as it is a conserved quantity. Several formulations of mechanics have been developed using energy as a core concept.
Work, a form of energy, is force times distance.
yes. in classical mechanics energy is useful property.
Where does sun gets its energy? From primordial big bang? Why did big bang originate?
sun converting its own mass into energy by fusion (converting in helium from hydrogen).
the measurement calculated to Einstein famous energy-mass relation equation. It squeezes some mass into energy- 4.3 billion kg/sec.
And it producing light almost 5 billion years.
what will happen when all the energy vanishes the universe?
I don’t understand where it states “Although heat is a form of energy, we cannot use it to generate electricity”. Don’t we use “Heat” to boil water to create steam that moves turbines to create electricity?
Chris, you are right but we cannot generate electricity from all heat form, like- you have a wire and in wire you transfer current with high voltage then wire will be heated due to resistance. So, in the wire we cannot use heat energy in another form of energy.
