What it calculates

The “Drag Force” calculator computes Resistance in N from 4 parameters: medium density (kg/m³), speed (m/s), cd, area (m²).

A standard physics formula used in educational and engineering tasks.

Example calculation

With parameters Medium density = 1.23 kg/m³, Speed = 30 m/s, Cd = 0.3, Area = 2 m² the result is 330.75 N (½·ρ·v²·Cd·A).

How to use

  1. Enter medium density, speed, cd and area — each field above is adjustable with a slider.
  2. Resistance (N) is calculated automatically as you type.
  3. Check the worked example below to see the formula applied to real numbers.
  4. Copy the result or bookmark this calculator.
