What is the key difference between a "free-fall" and a "shock" (or "zero-drop") tester?

A free-fall tester drops the sample itself from a height. A shock tester lifts and drops the impact base while the sample is stationary on top, simulating an impact to the underside of a large, non-droppable product. The choice depends on your test standard and product type.
