jjjjj Posted July 16, 2010 Share Posted July 16, 2010 Is it real or an idea? If it isn't real does that mean kinetic energy isn't real either? If kinetic energy is real does potential energy have to be real as well? Link to comment Share on other sites More sharing options...
ydoaPs Posted July 16, 2010 Share Posted July 16, 2010 What do you mean by 'real'? Energy isn't a substance; it's a property. Link to comment Share on other sites More sharing options...
ajb Posted July 16, 2010 Share Posted July 16, 2010 I think the correct way to think is that energy is a mathematical concept of our own devise, that is incredibly useful in our descriptions and understanding of our world. Link to comment Share on other sites More sharing options...
