SUMMARY
Terminal velocity is the constant speed an object reaches when the force of gravity is balanced by the drag force acting against it. To calculate terminal velocity for a sphere, one must know the object's mass, cross-sectional area, and the drag coefficient. The equation for terminal velocity (Vt) is Vt = sqrt((2 * m * g) / (ρ * A * Cd)), where m is mass, g is acceleration due to gravity, ρ is the air density, A is the cross-sectional area, and Cd is the drag coefficient. Resources such as HyperPhysics and Wikipedia provide further insights into this concept.
