Calculate the terminal velocity of a falling object when the drag force equals the gravitational force. At terminal velocity, the object falls at a constant speed with no further acceleration.
Enter your values below
Mass of the falling object
Depends on object shape (sphere ≈ 0.47)
Projected area facing the airflow
Air at sea level ≈ 1.225 kg/m³
Default is 9.81 m/s²
How this calculator works
Terminal velocity equals the square root of two times mass times gravitational acceleration divided by fluid density times drag coefficient times cross-sectional area.
