How Fast Is Terminal Velocity?


A free falling object achieves its terminal velocity when the downward force of gravity (Fg) equals the upward force of drag (Fd). Mathematically, an object asymptotically approaches and can never reach its terminal velocity. Terminal velocity is said to be is about 195 km/h (120 mph or 55m/s).
Q&A Related to "How Fast Is Terminal Velocity"
For a skydiver with parachute closed, the terminal velocity is about 200 km/h or 56 m/s.
How fast terminal velocity depends of the density and shape of an object and the density and viscosity of the liquid or gas that the object is falling through.
If the penny is in a vaccum, the penny has no terminal velocity because verminal velocity is when the resistance against the falling penny is equal to the force of gravity. So if
1. Determine the weight of the falling object. The easiest way to do this is usually to measure this quantity directly. You can also estimate weight if you know the construction materials
1 Additional Answer
There is no one given number for terminal velocity. It is determined by the way an object is shaped. For example a skydiver can change his terminal velocity by changing the form he takes. You can find more information here:
