*CONVERT POTENTIAL ENERGY TO VELOCITY*
======================================

Converts gravitational potential energy to the equivalent impact velocity using the kinematic relation v = √(2·g·h). Use this worker when you need to derive an initial or impact velocity from a known drop height and gravitational acceleration.

     - Drop or fall height (m, or consistent length unit); must be ≥ 0; defaults to 1 — override with the actual drop height of the scenario.

     - grav
     - float
     - 1
     - ✓
     - Gravitational acceleration (m/s² in SI; e.g. 9.81 on Earth); defaults to 1 — always override with the appropriate value for the unit system and environment in use.
