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.

Data

 
Area, A/ \( cm^{2} \)  289  249   190 169 130 88
 Terminal Velocity, v/ \( cms^{-1} \)  1.66 1.70 2.02 2.12 2.31 2.66
