Terminal velocity is the maximum speed attainable by an object as it falls through a fluid (air is the most common example). It is reached when the sum of the drag force ( F d ) and the buoyancy is equal to the downward force of gravity ( F G ) acting on the object.

La vitesse terminale, ou vitesse de chute stabilisée, d'un objet est la vitesse qu'il atteint lorsque la résistance du fluide dans lequel il se meut (l' atmosphère par exemple) compense son poids alors qu'il est en chute libre (on devrait dire chute aérienne) [ réf. souhaitée].
30 juin 2024 · Estimate the speed of a free-falling object through a gaseous or liquid medium using this calculator. Learn the factors affecting terminal velocity and how to use the formula with examples and FAQs.
24 janv. 2020 · Learn the difference between terminal velocity and free fall, two related concepts in physics. Find out how to calculate terminal velocity and free fall in different fluids and conditions, and see examples and references.
Find the terminal velocity of an 85-kg skydiver falling in a spread-eagle position. At terminal velocity, \ (F_ {net} = 0\). Thus, the drag force on the skydiver must equal the force of gravity (the person’s weight). Using the equation of drag force, we find \ (mg = \frac {1} {2} \rho C A v^ {2}\).
