Question

What does a skydiver achieve terminal velocity?

Answer 1

Based on wind resistance, for example, the terminal velocity of a skydiver in a belly-to-earth (i.e., face down) free-fall position is about 195 km/h (120 mph; 54 m/s).

Answer 2

Terminal velocity is the highest velocity which an object can reach as it falls through a fluid. In this case, the air is the fluid.

Here the sum of the drag force and the buoyancy is directly proportional to the downward force of gravity acting on the skydiver. Here the net force on the skydiver is zero and resultant zero acceleration.

Here the skydiver can reach the terminal velocity by falling freely under acceleration due to gravity through air.
