Drag Force

Theory & Logic

Theoretical Background

Physics describes the fundamental mechanism of the universe. The Drag Force Equation is an essential tool for understanding Drag Force Equation in quantitative terms. Calculate Fd = 0.5 * ρ * v² * Cd * A.

Mathematical Formulation

The relationship between the variables is governed by the following equation:

Result = 0.5 × rho × v × v × cd × a
Eq 1.1: Governing Formula

Variable Legend

Symbol Parameter Unit
rho Density kg/m³
v Velocity m/s
cd Drag Coeff
a Ref Area m²

Practical Calculation Example

Problem

Calculating the result when:

  • Density = 50 kg/m³
  • Velocity = 75 m/s
  • Drag Coeff = 40
  • Ref Area = 75 m²

Solution

Substituting into Eq 1.1:

Result = 0.5 × 50 × 75 × 75 × 40 × 75
