OUTPUT
Output
This section shows the terminal velocity equation along with its calculation with the given properties. The live velocity of the falling circle is given at the bottom as Velocity. The equation will change when buoyant force is disabled.
VT=−πrg|ρs−ρ|cdρ
VT=−π⋅1⋅−9.81⋅|10−1.225|0.2⋅1.225=33.22m/s
Velocity: 0.86 m/s
