Extension Springs are coil springs designed to be stretched from free length to a longer extended length to store energy, to provide a resistance to a pulling force or to provide a restoring force.  They are usually close wound, meaning that each coil is held tightly against the adjacent coil(s).  The force holding the coils together is called the initial tension.  This force must be overcome before the coils will start to open up as a stretching force is applied to the spring.
