... Heat Energy What is Energy? This is capacity of matter to perform work as a result of its motion or position in relation to forces acting on it. In other words, if you move a load “Mg” through a distance “h” you then have done a work Mgh! Energy associated with motion is known as kinetic energy; whi ...
