Reaching terminal velocity

Terminal velocity is the maximum velocity (speed) attainable by an object as it falls through a fluid (air is the most common example). It occurs when the sum of the drag force (Fd) and the buoyancy is equal to the downward force of gravity (FG) acting on the object. Since the net force on the object is zero, the object has … See more Based on air resistance, for example, the terminal speed of a skydiver in a belly-to-earth (i.e., face down) free fall position is about 55 m/s (180 ft/s). This speed is the asymptotic limiting value of the speed, and the forces acting on … See more • Stokes's law • Terminal ballistics See more • Terminal Velocity - NASA site • Onboard video of Space Shuttle Solid Rocket Boosters rapidly decelerating to terminal velocity on entry to the thicker atmosphere, from 2,900 miles … See more Using mathematical terms, terminal speed—without considering buoyancy effects—is given by • $${\displaystyle V_{t}}$$ represents terminal velocity, See more When the buoyancy effects are taken into account, an object falling through a fluid under its own weight can reach a terminal velocity (settling velocity) if the net force acting on the object … See more WebJan 16, 2024 · Use the terminal velocity formula, v = the square root of ( (2*m*g)/ (ρ*A*C)).
