Answer #1

The main reason for the use of dynamic rope is safety.

Dynamic rope offers more elasticity as compare to static. During fall of a climber he may get a sudden jerk or commonly called Impact force which is very much less in case of dynamic rope causing it to elongate more than static rope if same fall occurs.
