### 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 |
