Use the terminal velocity formula: (v_t = sqrt{frac{2mg}{rho C_d A}})
Identify the mass of the object, (m)
Use gravitational acceleration, (g approx 9.81 , text{m/s}^2)
Determine the fluid density, (rho)
Find the drag coefficient, (C_d)
Measure the cross-sectional area, (A)
Substitute all values into the formula
Calculate the square root to get terminal velocity, (v_t)
For a falling object in air, use air density for (rho)
For different shapes, use the appropriate drag coefficient for (C_d)
