Theory
the equation for the drag force on the square paper is may be assumed to be is the form of \( F = \frac{1}{2} \rho v^{2} C_{D} A \)
where F is the aerodynamic drag force
\( \rho \) is the is the density of the fluid
\( v \) is the speed of the object relative to the fluid
\( A \) is the cross sectional area
\( C_{D} \) is the drag coefficient – a dimensionless number.
