Energy is one of the most important and yet ambiguous concepts in physics; fortunately, the relationship between energy and work can aid in the understanding of many physics problems.

Energy - particularly mechanical energy - is often defined as the ability to do work, that is, to exert a net force on an object causing it to move a certain...
