You have asked the following question what is energy
We did the research for you and came up with the following aggregated content from all over the internet

Answers

We believe the answer should be around the following lines


  • In the international system of units si Energy is measured in joules [5]
  • In the context of chemistry Energy is an attribute of a substance as a consequence of its atomic molecular or aggregate structure [4]
  • In biology Energy is an attribute of all biological systems from the biosphere to the smallest living organism [4]
  • In other words Energy is invariant with respect to rotations of space but not invariant with respect to rotations of space-time = boosts [4]
  • After it has been transferred Energy is always designated according to its nature [5]
  • Over the whole cycle or over many cycles net Energy is thus equally split between kinetic and potential [4]
  • Energy is everything [7]
  • In quantum mechanics Energy is defined in terms of the Energy operator as a time derivative of the wave function [4]
  • Energy is also transferred from potential Energy to kinetic Energy and then back to potential Energy constantly [4]
  • On any time scales the uncertainty in the Energy is by [4]
  • Energy is the ability to do work [1]
  • In classical mechanics Energy is a conceptually and mathematically useful property as it is a conserved quantity [4]
  • Similarly in the case of a chemical explosion chemical potential Energy is transformed to kinetic Energy and thermal Energy in a very short time [4]
  • In special relativity Energy is also a scalar although not a lorentz scalar but a time component of the Energy momentum 4-vector [4]
  • In physics Energy is the quantitative property that must be transferred to an object in order to perform work on or to heat the object [4]

Energy transfer


  • In thermodynamics for closed systems the process of Energy Transfer is described by the first law [4]
  • Can be considered for the special case of systems which are closed to transfers of matter [4]

Energy can


  • Energy is a conserved quantity the law of conservation of Energy states that Energy Can be converted in form but not created or destroyed [4]
  • Be converted from one form to another in various other ways [5]
  • There are a lot of different kinds of Energy in the universe and that Energy Can do different things [2]
  • Then the total amount of Energy Can be found by adding [4]
  • Be neither created nor destroyed but only changed from one form to another [5]
  • Be transferred between systems in a variety of ways [4]
  • One form of Energy Can be converted to another form [7]
  • Also travel in the form of electromagnetic waves such as Heat light radio and gamma rays [2]
  • Mechanical and other forms of Energy Can be transformed in the other direction into thermal Energy without such limitations [4]
  • Be found in many things and takes many forms [2]
