Vertical Drop

How this simulation works

Use the Mass slider to set the object's weight (in kg) and the Air Resistance slider to control how much drag acts on it as it falls. Press Start to release the object from 50 m, Pause to freeze the fall mid-air, and Reset to return it to its starting height. With air resistance at zero, every object falls identically regardless of mass; with air resistance turned up, the object accelerates until drag balances gravity, after which it falls at a steady terminal speed.
